Beeptones is a simple win32 console application generates tones corresponding to each of the 6 open guitar string fundamental chromatic frequencies. The C application uses the kernel32.dll function Beep(frequency, interval) function which uses the PC System speaker or sound card, if present. It also provides a slow "strum" of the 6 strings, as well as a 50-tone random audio pattern. The interval between tones can be varied

Using the low-level
APIs which are supported on Win95 - WinXP it is possible to
develop tone-generation capability which works on all windows platforms with standard sound-cards.
The C application GuitarToner.exe is based on the sample code:
C. Petzold "Programming Windows" 5th Edn. 1999 p.1290 "SINEWAVE.C"
which has been modified to include buttons for fixed frequencies (rounded to the nearest integer Hz value) corresponding to each of the standard-tuning guitar string frequencies:
E6 82.41 A5 110.00 D4 146.83 G3 196.00 B2 246.94 E1 329.63Buttons for the standard A 440 Hz tone and the 1st string 12th fret (E12) are also included.

This Java applet uses Java Plug-in and uses the Java Sound API MIDI capability and a Java Swing GUI to play guitar strings, and a selection of chords. Chords can be played as all notes sounded together, or a slow "strum" checkbox plays each note sequentially, with all notes sounding during the strum.
