Part one:

Legato is the existential complaint and rebellion by the piano against its  mechanically percussive nature and thereby against the inevitable decline  in loudness of every note it makes once that note starts.

This is a way to help the student feel the connection between the various parts of their arm mechanism – from shoulder to finger tip.

In the steps that follows the teacher or the student can follow the instructions by doing the things described either to themselves by themselves, or the student and teacher can it to the other.

The hand has often, figuratively speaking, to divide itself into two parts so that it can pivot from the one side to the other.   From one to four fingers lying either on its right side subdivision or its left side subdivision.  What is most interesting about this process is that there is no firm line of demarcation between the two parts of the hand. Rather ,the hand can  subdivide itself at any point along its left-right span.

List of the possible ways of diving the five fingers into two parts:

A.B.’s lesson on 11/21/19: The Well Tempered Klavier, Book I, C Major Fugue

A.B. has been so much preoccupied with separating and preserving the identity of each voice in the fugue that it has led to awkward transitions from a note in one voice to a note sounding immediately thereafter in  another voice. This happens most especially when one voice has been sessile for a bit of time and then streams ahead again.  There is a virtue to practicing the connection between the current voice (on which focus is being maintained by the pianist) “obliquely” across the staff or staves to the first note that is flowing again in the voice that was tranquil for a while.

R.M.’s second lesson on the “Black Key” etude.

When you first read the notes of a new piece, don’t take any notes for “granted”. Don’t make assumptions about that note’s relationship with the note before it. Don’t look for patterns, especially ones that you may then be tempted to think repeat, when often in fact they don’t.
