piano
Non transposing instrument.
Scored in treble and bass clefs.

In commercial music the piano part should read as a short score. The pianist will improvise around what is written. Give the pianist all important chord changes and orchestral phrases. Include the electric bass part, stems down, on the bass stave. Include the vocal line in cue notes, stems up, an octave higher than standard, marking vocal entrances and exits with the lyric. Obligatory passages should be written, obligato.
