I don't know about you, but my little ones (including some 3rd, 4th, and 5th graders), have a hard time playing the BX and BM. When they kneel they are still too short and when they stand they are too tall. I've seen these stools around my school and I thought they would be perfect for the basses.
I bought them from Ikea for $7.99 each. I love that having these will encourage proper technique when playing the basses. I'll try and take some pictures of them in use this year.
What do you do to make playing basses easier for your smaller kids?
