20 SOUND 52, 1233/I
30 SOUND 46, 1394/I
40 SOUND 59,1086/I
50 SOUND 121,530/I
60 SOUND 80,1202/I

A higher value for duration will Increase the length of the note.

The formula, 64130/pitch, can be used to find the required ’duration' parameter to play a note of a specified pitch for one second.

See Four Octave Sound Range for parameters to generate specific notes of required frequency.
