play note () for () beats
The block will play any numbered note between C (0) and B♭ (130). While the block's keyboard graphic shows notes up to C (132), notes 131 and 132 cannot actually be selected, and a number outside the range given above cannot be typed into the block. If a number outside the available range is given to the block, through use of a variable or otherwise, the block will play the lowest or highest possible note, either 0 or 130, depending on whether the number is less than 0 or greater than 130, respectively.
As the block plays a note, it is widely used when a song is played with the music blocks. Some common uses for Play Note () for () Beats include:
- Easy sound effects (numbers up to 130 still work); very high and low notes make interesting sounds
repeat until <(x) = > play note (x) for (0.1) beats change [x v] by (-1) end
- Musical projects where you control instruments
forever play note ((mouse y) mod (129)) for (0.1) beats end
- Creating a song made by blocks
repeat (2) play note (62 v) for (0.5) beats end repeat (2) play note (69 v) for (0.5) beats end repeat (2) play note (81 v) for (0.5) beats end play note (69 v) for (0.5) beats
The Play Note () for () Beats can sometimes be tricky to get used to since the notes and rhythms are notated with numbers, unlike sheet music. These diagrams may help:
There are 131 notes on Scratch's keyboard, numbered from 0 (C-1, about 8.18 Hz) to 130 (B♭9, about 14917.24 Hz). Each note is 1 number larger than the previous, and the ratio of frequency is always 12√ (approximately 1.06), with A4 being 440 Hz.
