That would be absolutely far too stressful for the snake. Like DV said, they don't hear the same way people do, so I doubt it's appreciating your music in any way (sorry, snakes just don't have the capacity for appreciating the musical arts). Band practice would LOUD and BRIGHT with no place to escape to or hide, no hotspot, not enough humidity... and can often take hours. That would be tantamount to torture for the little critter.
