How is double bass typically notated?

• A. In bass clef, sounding an octave lower
• B. In treble clef, sounding an octave lower
• C. In bass clef, sounding at concert pitch
• D. In treble clef, sounding at concert pitch

Answer: (A)

Double bass notation is set up so players can read comfortably in its very low range. It is written in bass clef, but the sounding pitch is an octave lower than what is written. This octave transposition keeps the intervallic relationships and rhythm easy to read on the staff without piling on ledger lines. For example, a written C on the bass staff sounds as C an octave lower. While some modern scores may use treble clef with an indication of octave displacement, the traditional and most common practice is bass clef with the instrument sounding one octave lower than written.
