  Are you using the S3 or Activity Board block type?

  @John,
  
  Could you use the play tone block and use the duration to achieve the same thing? For instance, at 120 BPM, each beat would be 500 ms (1/2 second)? This could make a very interesting lesson in math and music. The block could be used for rests (or with a wait block).
  
  
  
  See this great resource at wiki - https://en.wikipedia.org/wiki/Tempo

  If you prefer the configuration of the play note block look and configuration - You could change the play tone block to an inline configuration as shown below. Both blocks are shown for comparison.

  Sure, no problem to achieve goal with play tones block. I use it for a student extension to investigate both duration and the physics of frequency.
  
  But for play block, having a duration doesn't have a meaning in music without a tempo (or as the DJ's say: beats per minute). I don't know if it would be easy to have a block that sets tempo. I think there might be one in Scratch.

  I know that one was being experimented with at one time...
  
  Here is something fun that could be Saved As to start a new bit of code or appended to code.

  Thanks, Whit.
  Sometimes brute force is a fine solution.
