It is the bass member of the violin family, which also includes the violin, viola and the double bass, which doubles the bass line an octave lower than the cello in much of the orchestral repertoire. After the double bass, it is the second-largest and second lowest (in pitch) bowed
The Well-Tuned Piano octaves, with nine notes extending the bass of the piano. Young describes the pitches of his tuning as being, "derived from various partials of the overtone series of an inferred low fundamental E-flat reference ten octaves below the lowest E-flat on the Bösendorfer Imperial".

Temperament actually involves the deliberate mistuning of pitches to make the overall octave more or less usable in various different tones. In "The Well-Tuned Piano",
