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.
