I would suppose that it is anathema for a musician to play out of tune, unless of course, you are playing something which requires alternate tuning where certain quarters would call that to be out of tune. Having said that, there are folks out there who have a perfect pitch, while others would need a little bit of help. Thankfully, technology has advanced to such a point where we can carry the $16.99 Pocket Tones Electronic Pitch Pipe in C about without missing a beat.
The Pocket Tones Electronic Pitch Pipe in C is so small that it is highly portable, and yet do not let its relatively diminutive size fool you. Being a tiny device, it can play pitches at the touch of a button. Sporting an extremely dynamic volume control, the Pocket Tones Electronic Pitch Pipe is able to go from super quiet for personal tuning to extremely loud for sectional (or larger) tuning. Not only that, one can also make use of it to play back fun and campy bleepy music. Carrying the Pocket Tones Electronic Pitch Pipe in C around is not an issue, where you can just place it in your gig bag, on your keyring, or basically at a place where you know where it is for sure.
