This mirror helped me unlearn bad technique habits I didn’t even know I had. No matter what piece I’m playing, but especially for warm ups and scales, I can always look at this mirror to see if my hand position is correct and to force myself to stop doing things I subconsciously do. Especially with remote lessons, when it can sometimes be hard to visualize what someone is saying, this helps me and my teacher approach technique. I also like that it’s shatter-proof, and that it has a cover, a folder to hold sheet music, and a smaller mirror.
