This is a collection of drones, an organ sound rich in overtones is used to help with tuning. These are not pure tones, so you will hear some pulsing as the overtones move in and out of phase. This more closely simulates a true playing condition than pure tones. You can download them by right clicking on these links and saving them ("save target as") on your computer or you can play them by just left clicking the link.

Be sure to read the section on how to use drones.
