A minor (abbreviated Am) is a minor scale based on A, consisting of the pitches A, B, C, D, E, F, and G. The harmonic minor scale raises the G to G♯. Its key signature has no flats or sharps (see below: Scales and keys). Its relative major is C major, and its parallel major is A major. Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. Johann Joachim Quantz considered A minor, along with C minor, much more suitable for expressing "the sad effect" than other minor keys (Versuch einer Anweisung die Flöte traversiere zu spielen). Whereas traditionally key signatures were cancelled whenever the new key signature had fewer sharps or flats than the old key signature, in modern popular and commercial music, cancellation is only done when C major or A minor replaces another key.
