AAAAAARRRRRRRRGH !!! ...
The HANON book ... when I was studying accordion, my teacher made all his students use the Hanon book ... imagine playing those left hand exercises on the accordion ... I should have practiced them MORE !!! ...

A few years ago I began to study piano with an excellent teacher/player in RI ... he had me using Hanon ... I soon developed a problem similar to Carpal Tunnel Syndrome and had to stop the exercises ... Keith Emerson had the same problem which almost killed his career ...
