Loud Practice

If people don't like to listen to you practicing that loud organ toccata at full tilt, you can always show them this card.
If that doesn't work, you can always tell them to be more quiet.
If that doesn't work, you can always practice it on a celeste, maybe with a 4 foot flute added, to give it a little definition.
If that doesn't work, one of two things will happen.
They'll either die or get over it.
