Basic use:

• select tuning (red tunings cause stress to the neck)
• select type (chord, scale or custom notes)
• select key
• select chord or scale/mode
• submit
• a short tutorial is at Youtube

Options/tips:

• use show as to show dots or note letters or degree
• use remember to display the last scale or chord again. Drag the upper image over the new one for comparison.
• use overlay for blue notes or red root notes
• use overlay to add minor or major pentatonic scales
• use custom notes for special notes
• use scale/mode: chromatic scale and show: notes for fretboard scheme
• use chords -> standard tuning for guitar tuning
• use enable midi for sound example, select instrument from menu
• for chords: O - open string, X - mute or don't pick string
• b: flat (halftone down)
• # or s: sharp (halftone up)
• for Internet Explorer, allow "Active-X" element for MIDI
• fingersets are not included - they are too individual depending on your fingers
• For the musical theory behind look at the basics
• Finally: learning scale diagrams does not automatically make you a good Blues guitar player...

Technical background

For those who are interested in php scripting:

The fretboard scheme is generated as an image using php. Scales and chords are stored as arrays containing the intervals. With an array containing all notes and an array containing the string notes all scale or chord positions on the fretboard are calculated and written as dot or note name. The php MIDI Class generates the midi files using the same arrays.
