Grouped into 4 modes

The current version has 28 Heptatonic scales which are grouped into four modes. Modes are Major, Melodic Minor, Harmonic Minor, and Harmonic Major. Please look forward to other types of Scales on the next version of Scalability.

Frequently Asked Questions

Below you’ll find answers to the questions we get asked the most about Scalability.

After selecting the note and scale, I tried to play the scale, but I cannot hear any sounds.

If you cannot hear the sounds of scale and chord, check the following.

  1. Sound settings
    Please check the volume of the mobile device.
    Apart from ringtones, you can adjust the volume of apps and music.
    Open Settings>Sounds, the volume of the application can be changed by changing the volume of items such as “Media” and “Music” that is different from the ring tone. You can also change from the screen that appears when you swipe from the top or bottom of the smartphone screen (Control Center for iPhone, Quick Settings for Android).
    It can also be set from the volume change button on the side of the smartphone device.
  2. Silent mode
    Please check if you are in silent mode.
    Scale Master does not emit sounds when the device is in silent mode(manner mode).
    On Android, Silent mode can be set by swiping down from the top of the screen and tapping sound.
    If you have an iPhone, it can be changed with the Ring/Silent switch that is placed on the upper left.
  3. Check the earphone
    When using earphones, you cannot hear from the speaker of the device, you can only hear from earphones. If there is no sound from the earphones, check if there are any problems with the earphones. The same applies to Bluetooth earphones.
Why are the names of the scale and corresponding notes different from the ones I know?

The names of the scales have variations.
For example, the Dorian b2, the second mode of the Melodic Minor is also known as Phrygian ♮6, Assyrian, or Phrygidorian.
There aren’t any strict rules for naming, so we tried to select a well-known name.
