Err, did you read the grub manual?
“The value of this option is passed directly to play.”
-- Command: play file | tempo [pitch1 duration1] [pitch2 duration2] ...
Plays a tune
If the argument is a file name (*note File name syntax::), play the
tune recorded in it. The file format is first the tempo as an
unsigned 32bit little-endian number, then pairs of unsigned 16bit
little-endian numbers for pitch and duration pairs.
If the arguments are a series of numbers, play the inline tune.
The tempo is the base for all note durations. 60 gives a 1-second
base, 120 gives a half-second base, etc. Pitches are Hz. Set
pitch to 0 to produce a rest.
