Okay all you musicians, I need some help.?

There can be ways to get around the use of thumb sometimes:

for clarinet, (B flat/A soprano) there are neck straps and special thumb rests that use the whole hand instead of the right thumb to support the instrument. Same with sax. (But the repertoire for clarinet is much better!!)

Percussion is also an option because there are so many different types of instruments and many different techniques.

Well, French horn is brass, but you only need the put the right hand in the bell.

All wind instruments need the right thumb to hold and support the instrument. Flute, oboe, clarinet, bassoon.

Trumpet needs thumb support for holding.

So French horn is probably the only instrument which doesn't need the right thumb.

Great instrument, too if you have a good ear.

I had a similar problem but it was carpal tunnel/tendonitis in the bowing hand. There's guitar which I don't think uses the right thumb or you could just avoid using the right thumb. The oboe is very light and you could use a strap to alleviate pressure.

Bass guitar.

You can play it with the three fingers of the right hand.

I think if you go to a music store you will find the voicing of the fretless bass to be very much like your cello. Once you adust to the different tuning you will be able to use your musical knowledge and really be a fine bass player

i agree with the person above me, but the piccolo is so small that supporting it wouldnt be an issue i dont think. Good luck!
