If you use Integer BASIC (faster and thus better suited for such stuff),
you can use the Programmer's Aid #1 helper routines to get sounds very
easily.

Integer BASIC (including the Programmer's Aid #1) can be loaded into any
64K or higher Apple II model, by simply booting a DOS 3.3 master disk.
After that, the commands INT and FP switch between BASIC versions. Both
commands imply a NEW, so don't forget to save your program before switching.

The only book on Integer BASIC that Apple ever published is the "Apple
II BASIC programming manual", a well-written tutorial-type book. It's
available for download at

The Programmer's Aid #1 has its own manual at

which unfortunately suffers quite a bit from a bad OCR job. But it's
still usable enough.
