Generate and explore musical scales. View notes, intervals, frequencies, and chord relationships for major, minor, pentatonic, blues, and modal scales.
The Music Scale Calculator generates notes, intervals, and frequencies for any musical scale starting from any root note. Choose from major, natural minor, harmonic minor, melodic minor, pentatonic, blues, and all seven modes (Ionian through Locrian) to explore the tonal palette of Western music.
Scales are the foundation of melody, harmony, and improvisation. Every song is built on one or more scales — knowing the notes and intervals of a scale tells you which notes will sound "right" over a chord progression, which chords naturally belong to the key, and how to build melodies that are coherent and expressive.
This tool goes beyond simple note listing. It shows the interval pattern, the degree names, the diatonic chords built on each degree, and the frequency of each note. Whether you're a beginner learning your first scale or an advanced player exploring exotic modes, this calculator makes scale theory visual and practical.
Instantly seeing the notes, intervals, frequencies, and diatonic chords of a scale is useful for practice, composition, improvisation, and theory study.
This calculator helps because it keeps the scale formula and the musical consequences together. Instead of only listing the notes, it shows what chords and interval structure grow out of that scale.
Scales are defined by interval patterns in semitones. Major: 2-2-1-2-2-2-1. Natural Minor: 2-1-2-2-1-2-2. Pentatonic Major: 2-2-3-2-3. Blues: 3-2-1-1-3-2. Frequency: f = f_root × 2^(semitones/12).
Result: C D E F G A B (W-W-H-W-W-W-H)
The C major scale has no sharps or flats. The interval pattern is Whole-Whole-Half-Whole-Whole-Whole-Half, producing the familiar do-re-mi-fa-sol-la-ti sound.
A scale is simply an ordered set of pitches within an octave. The interval pattern between those pitches defines the scale's character. The major scale's pattern (W-W-H-W-W-W-H) produces a bright, resolved sound. The natural minor pattern (W-H-W-W-H-W-W) produces a darker, more melancholic quality.
Every Western key signature corresponds to a major scale and its relative minor. C major and A minor share the same notes but start in different places, giving them different tonal centers and emotional qualities.
Each mode has a distinctive mood. Ionian (major) is bright and resolved. Dorian is jazzy and sophisticated. Phrygian sounds Spanish or Middle Eastern. Lydian is dreamy and uplifting. Mixolydian is bluesy and rootsy. Aeolian (natural minor) is sad and reflective. Locrian is dark and unstable.
Understanding modes unlocks a vast palette of sounds. Instead of being limited to major and minor, you have seven distinct tonal colors — and that's before exploring exotic scales like harmonic minor modes, whole-tone, and diminished scales.
While Western music theory focuses on 7-note scales and 12-tone equal temperament, other traditions use different scales entirely. Indian ragas are complex modal systems with ascending/descending variations. Arabic maqam uses quarter tones. Indonesian gamelan uses 5 and 7-tone scales that don't align with Western tuning. Studying these systems through their intervals deepens musical understanding.
The major scale. Every other scale and mode is defined in relation to it. Once you know major, minor is just lowering the 3rd, 6th, and 7th degrees.
Modes are scales built by starting on different degrees of the major scale. 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.
A five-note scale that removes the two most "tense" intervals from major or minor. The major pentatonic is degrees 1-2-3-5-6. It sounds universally pleasant and is found in nearly every musical culture.
The minor pentatonic with an added "blue note" (b5/augmented 4th). In C: C-Eb-F-F#-G-Bb. The blue note adds tension and character essential to blues, rock, and jazz.
The scale should contain the chord tones. Over Cmaj7, use C major or C Lydian. Over Cm7, use C Dorian or C Aeolian. Over C7, use C Mixolydian.
Harmonic minor raises the 7th degree of natural minor, creating a leading tone. Melodic minor raises both the 6th and 7th ascending, and reverts to natural minor descending.
