How are scale notes calculated?

Each scale is defined by a pattern of whole steps (2 semitones) and half steps (1 semitone). The tool applies these intervals sequentially from the root note to derive every scale degree.

What is the difference between a major and a minor scale?

A major scale follows the pattern W-W-H-W-W-W-H (W = whole step, H = half step), producing a bright, happy sound. The natural minor scale uses W-H-W-W-H-W-W, giving it a darker, more somber character.

Modes are scales derived by starting the major scale pattern from a different degree. For example, the Dorian mode starts on the 2nd degree of the major scale. Each mode has a unique interval pattern and tonal character.

What is the blues scale?

The blues scale is a 6-note scale built on the minor pentatonic with an added flat 5th (the "blue note"). It is widely used in blues, rock, and jazz improvisation.

Why do some notes show both sharp and flat names?

Many pitches have two enharmonic names (e.g. F# and Gb). The tool displays the sharp spelling by default. In practice, the correct spelling depends on the musical context and key signature.

Does this work for all 12 keys?

Yes. All 12 chromatic root notes are supported, and every scale type can be built from any root.
