Does anyone know why Hanon’s The Virtuoso - Pianist has asymmetric exercises?
In my copy of Czerny and Hanon (edited James Bastien), an explanatory note reads in part
\> Also the difficulties executed by the left hand in ascending, are exactly copied by the same fingers of the right hand in descending. This new style of exercise will cause the hands perfect equality.
Which seems an admirable goal. But it just isn’t true. It’s true of No. 1, but in No. 2, LH asc. plays 5-3-1-2-3-2-3-4 while RH desc. plays 5-\*2\*-1-2-3-2-3-4 (and a similar inequality in reverse: 1-2-5 vs 1-\*3\*-5). The notes played are the notes that would be natural to play with those fingers (i.e. the exercise has a third followed by a fourth ascending and a fourth followed by a third descending). Nos. 3 and 4 feature exactly the same discrepancy as No. 2.
Does anyone know why? Has this been discussed before? (I did try Google and didn’t find much.) #music #audio source
