A minor is the minor tonality, scale or chord based on the tonal center of A. The scale and tonality are made up of the pitches A, B, C, D, E, F, and G while the chord comprises of A, C, and E. The key signature is indicated by an absence of sharps and/or flats.
A minor's role in instrumentation
A minor is very well suited for guitar as it can utilize all six open strings and its tonic is considered one of the easiest diatonic triads on the guitar to finger.
Conversely, it is considered a difficult key for piano as it utilizes only the white keys and no black keys. This may explain why far more orchestral writings appeared in the key of A minor than solo piano literature.
Extra-musical associations with A minor
Johann Joachim Quantz considered A minor, along with C minor, much more suitable for expressing "the sad effect" than other minor keys
