Frequently Asked Questions

An interval is the distance in semitones between two notes. A major chord uses intervals of 0 (root), 4 (major third), and 7 (perfect fifth). These intervals remain the same regardless of which root note you choose.

A dominant 7th chord (e.g., G7) adds a minor 7th (10 semitones above root) to a major chord. It has a strong pull toward resolving to the next chord and is extremely common in blues and jazz music.

Chords are played with the root at octave 4 (middle C region). Higher chord notes may extend into octave 5. This gives a clear, mid-range sound that works well for chord recognition.
