With a formula of 1-3-5-7-9-13, it extends beyond the 7th for maximum harmonic color. This advanced arpeggio opens up sophisticated harmonic possibilities.
The C# Major 13th arpeggio is constructed using the interval formula 1-3-5-7-9-13, which means it contains the intervals Root (1), Major Third (3), Perfect Fifth (5), Major Seventh (7), Major Ninth (9), Major Thirteenth (13) above the root C#. The notes are C#, F, G#, C, D#, A#. An arpeggio differs from a scale in that it uses only the chord tones — the notes of the underlying chord played sequentially rather than simultaneously. The major arpeggio uses the root, major third, and perfect fifth — the same notes as the major triad. Key characteristics: Jazz Ballads, Contemporary.
