The deadline for the 2023 Group Christmas Project submissions has now been extended to Monday the 11th of December.
The problem with A-frames on the floor is, if you ever trip up, you can land on your fiddles. They are more or less designed to be hung from ropes by the scroll (you'll probably see that if you visit a few luthiers), so something on the wall out of harm's way is probably best. My music corner gets the sunshine after dawn for a few hours every day, so I don't want instruments exposed to that.
Rather than quote people on the subject of floor, wall, case, cabinet, table, carefulness, carelessness....
I have a 100usd flute that is permanently on a flute stand on the floor and I can pick it up any time I want and play around on it. I had an accident which broke the stand but not the flute! But last month I bought a 1500usd flute, and it spends all its time in its case and I never play it, lol! I need to because the key geometry is slightly different where the RH pinky is, and also the mouthpiece is slightly different.
So, back to protection vs accessibility!
