Learning the harmonica will be a journey and it may be interesting. From what I heard on youtube there are different techniques and sounds, but it may result in my gifting it to someone who can appreciate those tonals.

OTOH, I like the sound of the alto recorder I recently purchased, the problem is while it is supposedly sized for adult hands, maybe there's a fingering technique I'm missing because it does not fit my hands (and I don't have small hands). I'm going to try a soprano recorder and see how the higher tones sound compared to the alto. An alto recorder typically covers 349-2093 Hz and the soprano covers 523-3136 Hz; that's a significant shift. There's a chart at Recorder Frequency Ranges that may be useful. Per that chart, age related hearing loss starts around 2000 Hz. As I recall my hearing starts to significantly fail around 4000 Hz, so we'll see where this all ends.
