I love this app! I’ve used it daily for the past month or so after not using it for a few years and I have seen so much benefit out of it, and it’s also shown a spotlight on areas that I can improve upon as well.
I have some suggestions for the app that could be implemented in the future:
mp, p, and f dynamics to really make you conscious of what your dynamic output is. Maybe even adding a decibel meter?
A metronome, or maybe a timer to help gauge how long I need to play, especially on < > and > < figures.
The ability to change the amount of time that the long tone notes can be held out for.
Changing what dynamic shifts are available such as: p < mf > mp; f < ff > pp; etc.
Playing two notes or a beat or two (two quarter notes, or a beat of 8th notes, 16th notes, 8th/2-16th and 2-16th/8th note rhythms, and triplets. And then, even changing what notes are played with those varied rhythms (i.e. a beat of triplets playing A, D-flat, G-flat)
Instruments to include in the future: piccolo trumpet, E-flat trumpet, alto trombone, Eb/C tuba, etc.)
To challenge players that need to transpose throw in an option such as trumpet in D, horn in E-flat, treble clef trombone/tuba/euphonium, bass clef horns, etc.)
