Reference Library
How to use the reference library
When to read chapters and when to jump straight to a cheat sheet — and the four reference pages every guitarist should bookmark.
The reference library is the entire tutorial compressed into single-page cheat sheets. The chapters are where you learn; the reference is where you look up.
When to use which
| Situation | Go to |
|---|---|
| You’re learning a topic for the first time | The chapter (sidebar) |
| You want to play a Cmaj7 right now and forgot the formula | Chord library |
| You’re trying to remember what mode is “raised 4th” | Scale library |
| You’re writing a song and want a fresh progression | Common progressions |
| You need to find G♯ on the 5th string | Notes on the fretboard |
The four “tape on your guitar case” pages
If you bookmark only four pages in Fretwise, make them these:
- Notes on the fretboard — until the neck is memorised, you’ll come back here a lot.
- Interval cheat sheet — every interval with a famous-song reference. The fastest way to train your ear.
- Circle of fifths — the relationship map for every key.
- Common progressions — pick a Roman-numeral pattern and transpose it. Instant songwriting unlock.
How the diagrams work
Every fretboard diagram in the reference is interactive. Click any note to highlight it. Use the buttons to cycle the labels between notes, scale degrees, and intervals. The diagrams are SVG — they print cleanly if you want a paper copy.
Tip: the reference is keyboard-friendly. Press / to focus the search bar from anywhere on the site and type the chord, scale, or interval you're after.
