The A minor pentatonic scale: notes A C D E G, formula 1½ – W – W – 1½ – W. Scale degrees diagram and fingerings on the guitar and bass fretboard.
A scale is built from the root in whole and half steps. The order of steps defines its sound: major and minor differ only in where the half steps fall. Pick a scale and a root to see its degrees and steps, and the same notes in one position on the fretboard.
W — whole step (2 semitones), H — half step (the next fret on the fretboard)
