The major arpeggio consists of the root (1), major third (3) and perfect fifth (5), corresponding to the notes A, C-sharp and E. A fingering is formed from each of these notes, creating three positions called root position, 1st inversion (from the third) or 2nd inversion (from the fifth). To learn these fingerings, practice the major arpeggio exercise.
