Tenor banjo is commonly notated in treble clef. Music for most saxophones is usually notated using treble clef. It is identical to the treble clef transposed down 2 octaves. The F clef can also be notated with an octave marker. Bass clef is the bottom clef in the grand stave for harp and keyboard instruments. The same clef is sometimes used for the octave mandolin. Notes written in the treble clef are played with the hands. The trombone occasionally uses the alto clef, but not primarily. Woodley had a 'residency' performing at the Treble Clef restaurant in Prahran. The mezzo-soprano clef is very rarely used in modern contexts. For this reason, the terms G-clef and treble clef are often seen as synonymous. Staves with a neutral clef do not always have five lines. More often a bass clef is substituted for rhythm clef. Notes written in the bass clef are generally played by the feet. All note letter-names in this section refer to the bass clef.
