Hello Hans

Firts of all, I am french and I apologize for my poor English.

I was talking about an excercice where the software play chords and you have to play / indicate / select back what you heard.This is what is done with note or rythm dictate, but with chords - somehow like chords progression ...

Chords dictation ?

Mobile applications should be great, as much as theory tuition ...

Polyphonies would be great, for melodies and rythm, from 2 to 4 (even more ?) voices !!!
