## What is BlueNote2?

BlueNote 2 is an instrument for the iPhone, born of the desire to listen to the sound between minor and major.
The frequency of the chord is expressed visually.
Tap two or more sounds, but the interval of the pressed point and the frequency of the sound are inversely proportional, so you can sound like the interval you pressed as the string of a string instrument.
By the way, the timbre is a perfect sign wave.
As everyone's reviews increase, we are going to make it evolve, so we appreciate your kind appreciation.

### 2/5 — I hear no sound

*2021-05-17*

I’m using an iPhone 12 Pro and I hear no sound. How can I configure it to hear the sound?

### 2/5 — Needs more work

*2018-08-09*

It’s great to get an app completed and uploaded to the app store, but to get this used in songs it will need more work I’m sorry to say.
The best thing to add next is Inter-App Audio support so this app can be used with the other music apps in the iOS community.

### 4/5 — Interesting

*2018-01-22*

I like it but it crashes. Would be willing to translate to English but you don’t have contact info on your website
