For those curious, here follows the documentation from
the Microsoft QBasic Help file:

HELP: PLAY Statement (Music)
Plays musical notes.
PLAY commandstring$
commandstring$ A string expression that contains one or more of
the following PLAY commands:
Octave and tone commands:
Ooctave Sets the current octave (0 - 6).
< or > Moves up or down one octave.
A - G Plays the specified note in the current octave.
Nnote Plays a specified note (0 - 84) in the seven-octave
range (0 is a rest).
Duration and tempo commands:
Llength Sets the length of each note (1 - 64). L1 is whole note,
L2 is a half note, etc.
ML Sets music legato.
MN Sets music normal.
MS Sets music staccato.
Ppause Specifies a pause (1 - 64). P1 is a whole-note pause,
P2 is a half-note pause, etc.
Ttempo Sets the tempo in quarter notes per minute (32 - 255).
Mode commands:
MF Plays music in foreground.
MB Plays music in background.
Suffix commands:
# or + Turns preceding note into a sharp.
- Turns preceding note into a flat.
. Plays the preceding note 3/2 as long as specified.
To execute a PLAY command substring from a PLAY command string,
use the "X" command:
PLAY "X"+ VARPTR$(commandstring$)
Example:
'Play scale in 7 different octaves
scale$ = "CDEFGAB"
PLAY "L16"
FOR i% = 0 TO 6
PLAY "O" + STR$(i%)
PLAY "X" + VARPTR$(scale$)
NEXT i%

It was actually a quite useful and concise notation.
