Pro-Tone Pitch Pipe was conceived by the tour manager of a Grammy Award winning artist! The concept is simple: when you are ready to sing (for practice or performance) press the note on your voice part and wah-lah! You can also practice hitting certain notes by memory and then checking them against the tones on the app.
So what do you have to lose (other than your starting pitch/note in the song)!!! Get this app today :)
