After Britta Martini²⁾

I think singing is fundamental to music making. It is so helpful to be able to express a musical idea without having to play it on an instrument. I often have my students sing an idea before they try to play it. I like to make sure that the idea is clear before they try to play it on the instrument. This is vital in learning to play by ear. If you don't know what you're trying to play, you better stop and clarify before you try to play it.
