A few people on this forum have now bought the English translation of Moser’s book including me. It is an impressive work but I the learning progression is very unusual.
The major scale is introduced on page 102. Chords on page 86. The student is instructed not to proceed to them until after drilling intervals until they are second nature. When asked “what is the tritone up from E sharp” I’m supposed to be able to respond and play instantly.
I could understand doing this to get really good at playing by ear but book seems to be focused on reading scores from standard notation, which is
notoriously bad at representing intervals.
Can anyone explain?
