What is #fretflip?

Updated

#fretflip is an online guitar fretboard tool for viewing and editing scales and chords. You use it in a browser to explore the fretboard, create fretboard charts, and share them. It is aimed at people learning guitar and people teaching guitar, and it works with a wide range of tunings and string counts rather than only standard six-string guitar.

What you can do with it

The site describes itself as "The Internet guitar fretboard tool - view and edit scales and chords," with the broader goal to "Explore, create, learn and share." In practice that means:

  • View scales and chords on an interactive fretboard diagram.
  • Edit what is shown, so the diagram reflects the scale, chord, or pattern you care about.
  • Create fretboard charts of your own.
  • Share those charts with others.
  • Learn and teach — the page is organized around both "Learn guitar" and "Teach guitar."

Core features

Interactive fretboard

The homepage presents an interactive fretboard diagram you can try directly. The example shown is C Minor Pentatonic, and the diagram is editable ("Click to edit"). Notes are labeled both by name (C, D♭, D, E♭, E, F, F♯, G, A♭, A, B♭, B) and by scale degree (1, ♭2, 2, ♭3, 3, 4, ♯4, 5, ♭6, 6, ♭7, 7).

Scales and modes

Presets and scale options include:

  • Minor Pentatonic, Major Pentatonic
  • Minor Blues, Major Blues
  • The 7 Modes: Major / Ionian, Dorian, Phrygian, Lydian, Mixolydian, Minor / Aeolian, Locrian
  • Melodic Minor, Major, Minor, Augmented, Diminished
  • Superlocrian / Altered, Sym. Dim. / Half-Whole, Mixolydian b6, Lydian Dominant, Phrygian Dominant, Whole-Tone
  • All Guitar Scales, 3NPS and CAGED-shapes

Chords

Chord presets include Common Chords, Power Chords, 7th Chords, Shell Voicings, and Extended Chords. Chord types listed include Major 7th, Minor 7th, Augmented 7th, Diminished 7th, Dominant 7th, and Minor 7th flat 5.

Key / tonic selection

You can set the tonic or key across all twelve notes (C through B), which drives what the fretboard displays.

Learning and teaching material

The site includes structured learning content alongside the tool:

  • 1. Notes Explained
  • 2. Scale Degrees
  • 3. Harmonizing Scales
  • The CAGED System
  • Docs: Quick start guide
  • Docs: The interactive fretboard
  • Docs: The Complete Guide

There are also practice-oriented presets such as Major Triad Arpeggios, Minor Triad Arpeggios, Start Soloing, Modes and Pitch, Modal chord progressions, Find all Notes, Connect the pentatonics, and 4nps scale patterns.

Who it is for

  • Learners who want to see scales, chords, and patterns laid out on the fretboard and understand notes and scale degrees.
  • Teachers who want to build and share fretboard charts for students.
  • Players on non-standard instruments — the tuning list covers 7-string, 8-string, bass, ukulele, and alternate guitar tunings, so it is not limited to standard-tuning six-string guitar.

  2. Pick a preset (for example Minor Pentatonic) or click to edit and build your own.
  3. Choose your tuning and key/tonic.

A Log In option is present, which indicates an account system; the page evidence does not state what login unlocks or whether any features are paid, so treat account-related details as unconfirmed.
