beautiful

Good material. It is interesting to know that in (range a, b, c), c is the step size and Sonic Pi interprets it as such. However, it does not include 5 if we write (range 2, 5, 0.25, true), where true is the inclusive option,
We must necessarily place (range 2, 5, step: 0.25, inclusive: true).

Greetings!
