As a fellow musician, I can completely understand your devastation at losing your pitch and singing voice, @myjiggers1. Chemo is a systemic medication that attacks the fast replenishing cells, like blood cells, hair, nails, mucus, etc. Perhaps, the vocal cords also fit into this category.

I'm glad to hear that your issue isn't ototoxicity affecting your hearing. I am confident that if you can hear the wrong notes or imperfect pitches, your brain and ears will signal to your voice to correct it. You may have to work harder to get the right pitch, however. I also wonder if your vocal cords have been weakened by chemo, maybe you should be kind to your voice and not try for the same volume and number of hours of singing like you're used to. Hopefully, you can build that muscle again after chemo.

I'm tagging @hopeful33250 @jprust @hamila who may have experiences or tips to offer.

Myjiggers, have you considered consulting a speech language pathologist? When will you finish with chemo?
