Playing Priority Number One: Evenness

A.B.’s lesson on 8/22/19

First, an example of a playing goal that depends in turn on evenness of sound.

Let us say we want to ‘orchestrate’ a passage, meaning that the piano must be capable of uttering a variety of tone qualities.  Timbre change on the piano is most easily achieved as a secondary effect to changes in dynamic  intensity of the sound.  It is therefore advisable to first be able to level the  tonal playing field so that every note speaks with an equal volume,  regardless of its pitch range. Its duration, touch, attack, and way of connecting to the next note; all equal. Then, on this base of evenness, we can  orchestrate by sculpting a ‘relief’. So, timbre and orchestration at the piano  have a prerequisite evenness of sound, then that evenness can then be altered specifically.

If we make a list of important goals in our practicing, it would include both the ability to orchestrate and the ability to play evenly. However, evenness  has a priority over orchestration. Some goals simply depend on first  attaining mastery in some other goal.  Differences among sound, including  timbre, cannot be noticed in a constantly changing, uneven tonal  environment.

The same dependency on evenness as a prerequisite applies to:

  • Having a clearly articulated rhythm.
  • Crafting the ‘shape’ of a phrase.
  • Revealing the structure of a piece.
  • Responding to different emotional states through sound.

Before being able to play a crescendo or a decrescendo we need to have a foreground of – evenness, that makes it clear to a listener that certain notes are getting progressively softer or louder. Anything to do with sound, rhythm, fingering, and interpretation depends first on the  ability to play evenly.

Evenness is a complex amalgam of different facets.

  • The way one note connects to the next.
  • The loudness of the notes.
  • The same quality of sound regardless of each note’s duration.
  • The quality of the touch, and of the onsets of the sounds.
  • The extraction of the same resonance in the sound regardless
    of pitch range constant,

These evenness-es must then be combined when two hands are playing together, or whenever there is more than one voice occurring at the same time.

A.B. has a tendency to want to try perfect the tiniest details in a piece before addressing the more general and mundane matter of evenness. This  prioritization doesn’t minimize the importance of the details, it just postpones  their achievement for just a moment. For once the passage is even, A.B.  finds that the details are more easily  controlled and perfected.

Another example. Before choosing the ‘best’ fingering, be able to play the sequence of notes evenly regardless of the fingers being used. Then, the  final choice of fingering is made in a more revealing atmosphere, so that the effect of the passage is not primarily dependent on the fingering but that rather the effect is clear in the pianist’s mind prior to any particular  fingering.

Playing the “correct” notes would seem to be on an equal level of importance to ‘evenness’. Psychologically, though, trying to get the right notes to sound, without first demanding that they sound evenly, has the counter-intuitive effect of adding time to the process of learning the correct notes.

Once the pianist explores evenness, she or he becomes more and more sensitive to when evenness is not occurring. And with this growing awareness, the parallel question evolves: how fine a tolerance should go into setting the standard for the evenness. At what point does the evenness ‘click in’ as factor that brings a passage to life? And related to this is the question: how much of evenness is measurable on a sound meter? How  much is dependent on an actual conglomeration of factors that intuitively the ear must be aware of and process?

Ornaments, and the Seeming Length of Quarter Notes

A.B.’s lesson on 8/8/19
Prelude in Eb Minor, Book I.

#1

Interpreting the rhythmic notation in this Prelude and its reliance on half note beats rather than quarter note beats.

In this Prelude the difference between the shortest duration notes and
the longest duration notes spans an unusually wide variety of
intermediate rhythmic values. The shortest duration note is the 32nd
note as in measure 38. The longest a dotted whole note in measure 40.
This wider than usual range may have been one factor in Bach’s choice
of half note beats rather than quarter note beats.

Historically, with the passage of the centuries, a note like the whole
evolved from being a note of relatively shorter duration on a clock to
a note of a longer duration on the clock. Reflecting this change is
the difference between the older name for a whole note, that of
“semibreve”, or half of a brief note, to whole note, which is more at
suggesting the nature of a “whole which is the sum of the parts”.
During this historical process, at no time, did a whole note equal
anything more or less than the duration of two half notes (assuming a
constant tempo). The RATIO of durations between rhythmic note values
(quarter to half, half to whole, whole to half, etc.) has always been
fixed.

While this relative ratio never changed, the ‘absolute’ values of the
notes, on the clock, as the decades and centuries passed, underwent a
sort of slow continental drift, making the difference in absolute
values get further and further apart from each other, each note itself
becoming longer and longer. A note originally intended to portray a
subjectively short duration in consciousness, grew and grew in until in
our century it is usually meant to portray a much longer duration on
the clock. Other notes grew similarly, only they kept their fixed
ratio of duration when looked at from one to another.

A thirty-second note would not have even shown up on the chart at the
time when whole notes were ‘semi brief’, the thirty seconds lay beyond
the horizon, out of radar range, existing only mathematically in the
realm of possibility, perhaps coming to tangible existence sometime in
the future.

In addition to the whole note being called ‘semi’ (in the sense of shorter than) a ‘brief’ note, the following notes all had names that reflected the
fact that a various times each one in turn had a name suggesting
shortness.

Whole note semibreve semi brief, shorter than a short note; half note minim the least or most minimal duration; eighth note quaver a quiver, single flutter of a bird’s wing; sixteenth note semi quaver less than the briefest flutter – almost undetectably short; thirty-second note demi-semi-quarter shorter than the shortest of the shortest

The original name for a quarter note, which was ‘crotchet’, had more
to do with its visual appearance than its subjective duration (possibly a “hooked” note – the hook I’m assuming being the stem).

Of course, all of this is varied by the ‘tempo’. No note, at any
historical time, had a fixed duration. A fast tempo would render, for
example, a sixteenth note, into a note of very short duration, while a
slow tempo will take the same sixteenth notes, and stretch its
duration.

One might imagine a line of notes from long to sixty-fourths, and
over the centuries the “Ancient of Days” acknowledges, or anoints,
first one than the next, with the epithet “you are the shortest of
notes in duration”.

#2

With such a wide range of durational values to choose from, it is
sometimes difficult to maintain a single, even tempo through out the
piece, especially when rhythm switches back and forth from relatively
longer notes (whole notes and longer) to relatively short notes
(sixteenth notes and shorter).

Let us assume that as the pianist you are counting out loud while you
are playing this prelude, and your particular goal is to use the voice
to steady the tempo. One way in particular of defining this goal is
to say that no quarter note, anywhere in the piece, is longer or (in
particular) shorter than any other quarter note in the piece.

Many people encounter difficulties counting out loud and coordinating
the notes with the spoken counts. There is however one sure fire
principle to help things along. Be suspicious if you notice that your
voice momentarily fades out while playing. This is almost always a
sign that there is uncertainty about the rhythm at that moment. It
usually occurs when shifting to longer notes from shorter notes or vice
versa.

You need only to be aware enough of the sound of your voice to hear
that it is fading out or disappearing altogether. You can reliably
assume that these are the moments when your tempo has sped up or
slowed down.

When the rhythm in the prelude switches from sixteenth notes or
thirty-second notes abruptly to quarter notes or half notes, an almost
‘existential’ crisis may develop in the player’s mind. The quarter or
half notes seem to be unusually long, almost “too” long. They seem
naked and alone and want to cover up their full duration by a bit of
shortening. “No, these notes couldn’t possibly be meant to last as long as this”. The result, without usually being conscious of its happening, are that the longer notes speed up. In fact, the longer the pianist holds out the note, the faster an inward tension builds up urging the note to end so that the next note may start.*

It is like, in special relativity theory, the player’s local clock,
when traveling faster relative to another observer, goes through a
relativistic shift compared to the slower observer. To this observer
the notes seem to grow shorter and shorter, while to the pianist’s
observations are that no apparent change in duration has occurred.

What can the pianist do to ameliorate this situation? After all, it would be awkward to have a metronome loudly ticking on the piano when
performing the work.

There are several things that can be done by the pianist on a
subjective level to keep the tempo even. They share the common idea
of the longer notes being subdivided mentally into a string of shorter
notes.

When playing quarter notes, for example, sixteenth notes can be felt
to be pulsing inside the quarters. The outside observer may not hear
these separate sixteenths, but they are quite vivid to the performer,
so much so that the pianist can ‘hear’ the sixteenths as vividly as the
quarters.

Here is one particular technique that I use at lessons. As soon as
you the pianist’s voice is about to loose its certainty in
enunciating the counting syllables, have the pianist try eliding,
that is, prolonging the sound of one syllable into the beginning of
the next.

An example. If, in a particular measure, the voice falters or fades
out, at just the time when the pianist is supposed to say the counts
“three and four and”, do as follows.

Change the word “three” into a series of three separate elongated
sounds (thhhhhh, rrrrrrr, and eeeeeee), Moreover, have each of the
each sound gradually morph into the next
(“thhhHHHH->rrrrRRR->eeeeEEE). And, if we prolong the “eeeeee” sound
right up to the boundary with the word “and”, then the entire third
beat becomes (voice-wise):

thhhhh->rrrrrr->eeeeeeeeeeeeeeeeeeee->aaaaaaa->nnnnnnn->dd.

Doing this serves a double purpose. It makes the pianist more, rather
than less, aware of the sound of their voice when counting out loud.
Secondly, if a count is parceled out among a series of short duration, this system of counting and eliding allows the pianist to keep better track of when exactly each shorter note is supposed to begin and end.

#3.

What about ornaments. Should we add them in right from the start?

Every rhythm, whether or not that an ornament, can be reflected through a prism that will separate it into smaller component rhythms. each
component rhythm sheds light on the printed rhythm both musically and
in terms of physical ease of execution.

Let us take a banal example: four quarter notes.

Using these abbreviations:

w = whole note
.h = dotted half note
h = half note
q = quarter note

And by tying together certain of the quarter notes to others, we find
these rhythms ‘inside’ the four quarter note rhythm.

w
q .h
,h q
h h
h q q
q q h

and by subdividing certain of the quarter notes we find these rhythms
as well ‘inside’ the four quarter note rhythm.

e = eighth note

e e e e e e e e
h e e e e
e e e e h
etc.

Each has its own sense of pulse and emphasis. The ideal rendition of
the original rhythm (q q q q) would reflect the special properties of
each and every one of the sub rhythms.**

#2 Ornaments in particular:

A.

The first thing to do is leave out the ornament entirely, Simply hold
out the single note out that the ornament is applied to. Hold it for
its full written value. This accustomed the body to the exact duration in which the various notes of the ornament will unwind through time plus any remaining duration of the main note. Adding in the notes of the ornament later, feels to the body like filling in a pre-made compartment of time.

B.

The next step is to actually play the ornament without any rhythm to
it at all, or in effect, with every note of the ornament held for the
same duration as every other. And, at the same time, elongating that
common duration, so that the ornament will sound like a slow melody.

Expanding the ornament into a lyrical melody is related to what we
said above about rhythms containing rhythms, plus its reverse: that
smaller rhythms join or fuse together into larger rhythms (in our
case, until the ornament turns into one held note whose duration is
the sum of all the shorter notes plus the written note). Or to misquote a favorite satirical poem in biology and bacteriology books: big fleas have little fleas, and little fleas or littler flees, and so on to infinity.

C.

As we proceed on towards playing the complete ornament, begin by
combining groups of notes in the ornament together into just one held note. Then stage by stage add in more of the details of the ornament. Each stage
nestles inside or embedded into the previous stage.

* Sometimes this anxiety increases exponentially with time rather than
linearly.

** It is like the color of a star. It may be emitting light at many
different frequencies (or colors) but the predominant effect of all of
them together is a single color.

A Chopin Nocturne; the Boundary Between Heard and Imagined Sound

S.B.’s lesson on 7/11/19: Chopin: Nocturne in C Minor, Op. 48 / 1.

#1. Beginning

The piece begins with two solitary c-s (c2-c3). A beat later C is joined by other notes belonging to a C Minor chord. At what point do we begin to hear or sense the full C Minor chord? We may think that one beat is not a long time. That very soon after we play c2, any ambiguity as to identity of the harmony during the first half of the measure will disappear, as the hands complete the C Minor chord on the second beat. But subjectively that first beat can last a long time. Either the pianist, or the listener already quite familiar with the piece, must imagine the rest of the C Minor chord sounding (c2–g3-ef4-g4–g5) before the second beat arrives, while only the C naturals on the first beat are still in the outer ear.

The same applies for all the other half measures in the opening. The pianist should have a pre-vision (sic) – a “pre-audition” – of the full chord in their imagination, as if it is already fully sounding into their outer ear. One of the most subtle and masterly things a pianist works with when constructing with sound is the middle ground between heard and imagined sound. Memory and anticipation are always weaving together in the consciousness of duration in time. The boundary between the two should not be fixed and definite, but blurred. What the pianist imagines has a tangible effect on what the listener thinks they are hearing.

#2. Things that can spoil a legato in a long phrase.

The first phrase is four measures long. There are several places within it where it requires increased additional focus to keep the sense of legato flow alive.

A. Measure one and the first half of measure two

The presence of a rest can indicate two very different things. One
is to force a break in a melody: to consider something as being two
separate things rather than one continuous thing. The other is to
increase the sense of connection in the melody by having to overcome
an obstacle or gap that has been superimposed upon the melody. It is
like the electric charge crossing the gap in a spark plug. It is like
water building up behind a dam. A pressure, or force, builds up
behind the stoppage of the first note which makes going on to the next
note even more inevitable and accomplished with greater momentum.

B. The first two notes in measure two

The g5 comes in as a quarter note but starts on the and of one. If
you think of this quarter note as two eighth notes tied together, the
easiest place to loose the legato is as the first half of the quarter
note ties over the end of beat one into the first part of beat two.
It is in effect a tie to connect two beats. The force of the flow of
that sound has to spill over the boundary between the two beats. It
is not enough to hear one note, but as if that note began a sudden
crescendo just prior to its second half. It is the rhythm and the
meter that forces this imaginary crescendo upon the otherwise formless
sound that lasts two eighth notes.

C. The tied d5 in measure two going to the ef5.

Immediately after the imaginary crescendo during the first d5 in
measure two, we encounter another situation which can attenuate a
continuous legato. It occurs when a relatively long note is followed
by a relatively short note. In this case the first d5 of the measure
is the longer note, lasting for three sixteenths, and the following
ef5 not only is one sixteenth long, but it also comes in after a tie. A
double whammy.

We normally rely on there being enough resonance left to a note to
effect a soldering of one note in a legato to the next. Otherwise the
sudden change from the end of a longer note. which has already
decayed, to the sudden attack of the next note sounds too much like an
sudden accent and defeats the attempt at the legato. To overcome this
difficulty, the pianist’s ear must track the full duration of the
longer note, instant to instant and, in their imagination, sustain
(prop up) the loudness of the note so as to counterbalance the
decrescendo of the decay. Then they must connect this heightened form
of the end of this note not to the attack of the following note but
the level of sound the next note will have a moment after the attack.
Even when it is just a short note.

D. The repeated c5-s in measure three.

When playing the same note several times in row, do we let the legato
come solely from the pedal? Or do we use the more cumbersome but
elegant way of controlling the key dip and not resorting to the pedal.
Or perhaps some of both? This is the pianist’s decision. The purer
legato is always attained by manipulating the key in question so that
at the instant that the key is released, and a minimal fraction of
inch before it reaches the top of the key dip, the arm is already
overriding the upward motion of the key with a strong downward force
to send the key down again.

E. The g4 in measure four going to the the grace note bf4.

This falls under the heading of a relatively longer note going to a relatively shorter note (see letter ‘C’ above). Pianists will often inadvertently make the legato connection occur from between the note before the grace note to the note to which the grace then goes to. The more sublime legato connection is from the note before to the grace note itself, in spite of its very short duration.

#3. Other things contributing to maintaining constancy of flow in the piece.

A.

The way the pianist releases a chord unintentionally affect the way they
attack of the next chord. Thus, when playing the chords on the offbeats in beginning of the piece, don’t “telegraph” the release of the left hand chords into the attack that started the same chord.  Regardless of the duration the pianist wishes to hold these chords (some editions show them staccato) there should be two physically dissimilar gestures, one for the attack, one for the release, with a stasis in between them.

B.

The middle section of the Nocturne, where a series of wide chords is
arpeggiated from one hand into the other. The broken chord is
difficult, regardless of the distances between the notes and fingers,
if the chord is first rendered as a melody of single notes, starting
with the bottom note written in the left hand for that chord, and
ascending leisurely a pitch at a time until finishing the melody with
the highest note of the chord that is written in the right hand. The
pedal can be kept down. The finger that has just played one of the
notes can come off that note the moment the next finger has started
its note. This discourages over-stretching the hand when the melody
is turned back into a chord.

C. The section with double octaves.

S.B. has a small hand and was reluctant to learn the piece.

She pointed out that her fingers are hyper-flexible. Watching her
carefully as she played the octaves, I found myself wanting to say, for
the first time to a student, “You may want to not use all  that flexibility.”

I called her attention to the shape of her hand and wrist when playing
an octave, in particular along the length of the fingers and a projection of that axis through the hand and wrist. Her wrist was elevated. The third knuckles of her fingers were at a lower altitude in comparison to the wrist, but because the third knuckles hyperextended to a strong degree her second knuckles were at a much higher altitude than the third knuckles.

I suggested that this contour had innate disadvantages when seeking the greatest extension between the fingers without inducing tension. That without coercing anything, she could encourage a shape from wrist to fingers that was more in the spirit of being like, or in the direction of a
straight angle. To coax her hand into that shape, she could rest the
three middle fingers on the surfaces of random keys lying in between
the pinky note and the thumb.

This improved the sound of her octaves, as well as their quality of
resonance, evenness, and her alacrity in changing from one octave to
the next.*

* Often when I said I noticed a difference she did not. Sometimes it
wasn’t so much that she didn’t notice the improvement, but that the
improvement was short of her ultimate goal and desire. This time
however, she smiled and said, “Oh, that was much better, and much
easier too”.

Creating Harmonic Clarity

Bach:  C Major Prelude, Book I, Well Tempered Klavier

Part of A.B.’s quest is to play the notes of this prelude “evenly”.  Achieving this has to do with the chord outlined by the notes of each measure, and the balance of the notes in the chords in creating a clear impression of that chord as a whole.   To make this chord more obvious to the ear, the player, when practicing, can “densify” each chord:  if there are openings between adjacent written notes in the chord to squeeze in additional notes from the same chord, add those notes in.   For instance in measure 2, there is room for an f4 between the d4 and a4.  If we add in that f4, we create the denser five-note chord: c4 d4 f4 a4 d5.  We can take that chord a step forward and add a c5 between the a4 and the d4, forming a six-note chord.  The chord has been a D Minor-7 chord the entire time, but the additional chord tones just make it stand out more clearly to the ear what chord it is.  Do this for every chord in the Prelude when Bach’s written notes allow for such additions.

An equally valid technique to add density to the character of a chord is add in chord tones in lower and/or higher octaves not used in the printed chord.  In this form a chord could contain 8 – 10 notes, or by adding the pedal, larger numbers of notes, spanning the low bass to high treble.  In this form, the “quality” of the chord reveals itself at its most obvious.  This technique, helps “set” the sonority of the written chord inside a larger entity to which it in turns belongs.

Whatever are the sound characteristics and the mood characteristics of the individual chord, they become in this manner magnified to the ear.  From this form of the chord we can then re-compress the chord (through the aesthetic equivalent of a ‘trash compactor’) without losing any of the sound ‘material’ present in the larger version of the chord: the larger instance of the chord being condensed into a smaller chord without losing any of the fullness or meaning of the uncompressed version of the chord.

Changing the loudness of one note in a chord

By controlling the relative loudness of each note in a harmonic chord, we are doing what a composer does while writing a symphony, and decides which instruments should play which notes in a chord: more instruments on this note, fewer on that note.

More prominence or less prominence given to the extension of the chord into a higher octave. Rarely does the composer put the same number of players on each of the notes in a chord.

When we do this ‘orchestration’ at the piano, the cause, and the effect are more subtle. Yet the result does mimic orchestration. This is because if we play a particular note twice, once softly, and once loudly, though the primary difference in heard in terms of dynamics, there is a secondary change, which we can notice if we focus on it, in terms of the relative loudness each overtone of that note has as compared with the loudness of each of the other overtones.

Acoustically, this is what gives rise to what our brain interprets as a change of ‘timbre’, or ‘tone quality’, or instrumental quality: that which makes an oboe playing middle C at mezzo forte sound different than a violin playing middle C at the same loudness. This change of timbre is somewhat noticeable when listening to a single note, but when it is multiplied over the various notes of a chord, the difference in the overall timbre of the chord changes more noticeably. Even when we play all the notes of a chord with equal intensity, the result is not what we might anticipate. Each note in the chord is under the “spell” of the harmonic progression. If a note happens to be the ‘third’ of the chord, it will have a relative predominance of effect over the root and fifth. This explains why if we are, for example, in C major, and have a V chord going to a I chord, we can omit the fifth in the I chord. Even though we have left just the root(s) and third(s) there will be no doubt as to whether the chord is a I chord or a vi chord, since both C E G and A C E share the C and E in common.
