The play note block plays a tone, using a note, frequency, and volume determined by the user. The Scribbler robot will not run the next block command until the note finishes playing.

play tones

The play tone block plays one or two tones for a specified period. Both the duration and frequency are set by the user. Either frequency can be left at the default 0 Hz, for silence, or set up to 10,000 Hz. The duration can be set between zero and 8,000 ms. For values outside of the valid 0 to 10,000 Hz and 1 to 8,000 ms ranges, the block will use the closest value that is within range. The Scribbler robot will not run the next block command until the note finishes playing.
