When I was a kid I wanted to learn to play the guitar. Logically, my mom signed me up for guitar lessons. When the day of my first guitar lesson arrived, the teacher showed up with . . . . an accordian. Yes an accordian. This was not a mistake. Apparently my would-be music teacher thought the best way to introduce me to the notes of music was to show me on an accordian.
Today, I play neither the guitar nor the accordian. Why am I telling you all this? Simply to introduce you to Toots Thielemans. He is an accordian player who plays the harmonica and makes it sound like an accordian.
To the best of my knowledge, he does not teach guitar.
