Blues Guitar Chord And Scale Generator With Fretboard Scheme

If you miss a chord, scale or tuning just email me!

How to use:

• select tuning (red tunings cause stress to the neck)
• select type (chord, scale or custom notes)
• select key
• select chord or scale/mode
• select display (dots or note letters)
• submit
• use overlay for blue notes, red root notes
• use overlay to add minor or major pentatonic scales
• use scale/mode: chromatic scale and show: notes for fretboard scheme
• for chords: O - open string, X - mute or don't pick string
• b: flat (halftone down)
• # or s: sharp (halftone up)
• enable midi for sound example, select instrument from menu
• for Internet Explorer, allow "Active-X" element for MIDI
• use chords -> standard tuning for guitar tuning
• fingersets are not included - they are too individual depending on your fingers
• use custom notes for special notes
• 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.
