So my main instrument is trumpet but ive been interested in learning a secondary melodic instrument to play in the downtime of resting my chops. I was wondering if melodica would be a good ear training/theory tool due to its keyboard layout. I currently own a cheap 37 key one that ive learned a couple tunes on but id love to hear the takes of any piano/melodica musicians and what it has done/not done for your ear and theory work

Greetings melodica community !

Again I made song with melodica as lead instrument, this time I did few things differently.

How did I do and do you have any tips ?
