Sadly, in a way, I started playing the chromatic because I was encountering physical limitations playing other instruments I use. But after a while it became my favorite instrument to play and practice with because it's convenient, versatile and it seems to suit me.... Don't know exactly why, but at least in certain styles of music, particularly jazz, I play it better than the guitar, fiddle, mandolin, ukulele, and banjo - all of which i have played and performed with professionally or semi-professionally. And chances are it will be the instrument I will most likely still be able to play as I age..
I experienced an awful fall in early July - broke 5 ribs, lacerated my liver, and eventually had a minor stroke and two grand mal seizures. I can still practice and perform on the chromatic - but not yet with any other instrument. It's been nearly two months and my back is just getting healthy enough to maybe play the fiddle next week! But in the meantime I've learned two interesting tunes on the chromatic - Goodbye Pork Pie Hat amd Lines for Lyons as well as spending time refining several Hoagy Carmichael tunes.
If it weren't for the chromatic, I might not have been able to play any music for at least a month - maybe longer!
Carry on, Y'all
