Frequencies for sounds can be inconvenient to figure out, as in the last lesson. So, we also have a function called music() that allows you to play sequences of notes, referenced by their name, like C, A, or Bb (B "flat").

Move the mouse over a dotted box for more information.

In sum, just put a bunch of notes in a string, and separate each by a comma. There are a few special cases of the "notes" too:

• Ln, where n is a number (like 0.1, 1, 0.05, etc.) specifying how long (in seconds) the notes that follow should be held for. Example: music("L0.1,A,B,C,L0.5,A,B,C")
play()
• On, where n is a number (0, 1, 2..8), and "O" is an "oh" (not a zero). The number you put in for n stands for an octave that all subsequent notes should be drawn from. Middle C is in octave 4. Example:
music("O4,C,O5,C,O6,C")
play().
• Pn, where n is the number of seconds to pause for (this would be a "rest" in music). Example:
music("A,P0.5,A,P0.5,A,P0.5")
play()
