Altered Scale Piano Reference With Notes & Intervals
🎹 The altered scale, also known as the Super Locrian scale or the altered dominant scale, is a 7-note scale that's based on the Locrian mode and is also the 7th mode of the melodic minor scale. Compared to the Locrian scale, the altered scale also has a flat 4th scale degree. That means that the altered scale has all of its non-essential tones (e.g.: all expect for the tonic) flattened compared to the major scale: 1 - b2 - b3 - b4 - b5 - b6 - b7.
The name altered scale can be confusing as it's also used as the name for a number of other scales that are altered.
