With a formula of 1-3-5-7-9, it extends beyond the 7th for maximum harmonic color. This advanced arpeggio opens up sophisticated harmonic possibilities.
The A# Major 9th arpeggio is constructed using the interval formula 1-3-5-7-9, which means it contains the intervals Root (1), Major Third (3), Perfect Fifth (5), Major Seventh (7), Major Ninth (9) above the root A#. The notes are A#, D, F, A, C. 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, R&B, Neo-Soul.

- Playing too fast before understanding the arpeggio's sound
- Not connecting the arpeggio notes smoothly (arpeggios should flow)
