Great intonation workout

I’ve been using this app for years to practice intonation using slow scales. I only wish they could go even slower than half notes at 60.

Response from developer

New update coming and will make sore this is in there.

Only 1 octave.

As is it’s pretty useless. Plays only one octave. Good idea, but the developer evidently has pretty much abandoned the app anyway.

Excellent

I’m very happy with this program because it does what I need it to do: figure out what key a song is in!

Volume

I do wish the drone was a bit louder.

Practice tool

It’s a great practice tool. Scale visual gets out of sync with the corresponding notes. it would be nice to be able to play two octaves.
