What is a Music Scale?
A musical scale is a set of notes arranged in ascending or descending order within an octave. Scales define the tonal palette of a piece of music, shaping its mood, emotion, and harmonic possibilities. Every melody, chord, and solo draws from the notes of a specific scale.
The most common scales in Western music are the major and minor scales, each with 7 notes. Beyond these, hundreds of scale variants exist across different musical traditions, from the pentatonic scales of blues and folk music to the exotic scales of Middle Eastern and Asian traditions.

Frequently Asked Questions
How many notes are in a scale?
Most scales have 5 notes (pentatonic), 6 notes (blues, whole tone), or 7 notes (major, minor, modal). Some scales like the diminished scale have 8 notes. The octave (12 semitones) can be divided many ways to create different scale patterns.
What is the difference between major and minor scales?
Major scales have a major third (4 semitones from root), giving them a bright, happy sound. Minor scales have a minor third (3 semitones from root), giving them a darker, sadder quality. The key difference is just that one interval.
What are modes?
Modes are scales derived from the major scale by starting on a different degree. Dorian starts on the 2nd degree, Phrygian on the 3rd, Lydian on the 4th, Mixolydian on the 5th, Aeolian (natural minor) on the 6th, and Locrian on the 7th. Each mode has a unique interval pattern and mood.
How do I know what key my song is in?
You can use BeatKey to detect the key from an audio file automatically. Or identify the key by ear: find the note that feels most "at rest" when the song resolves, then determine if the overall feel is major (bright) or minor (dark).
