Guitar Fretboard

Highlight notes or a scale across the fretboard, switch tuning where supported, and use the tuner or interval finder for pitch-focused practice.

Custom tuning, scale & chord practice map

The fast fretboard above remains first. This optional map reuses WTA179Music for pitch classes and note playback, adds practical tuning presets or custom six-string tuning, more scale/chord overlays, degree labels, 12–24 frets, and CSV handoff.

Practice-map evidence

Visual pitch-class labels use a compact sharp-name spelling; verify notation spelling separately when required.

Practice and playback notes

connects timing, tuning, pitch reference, virtual instruments and music-theory tools without requiring an account. Existing interactive engines remain intact while the new workflow makes it easier to move from a practical task—keep time, tune, play, identify, transpose—to the next relevant tool.

Audio and theory boundaries

Microphone pitch detection depends on the device, room and signal quality. Equal-tempered frequency math does not measure a real instrument, and chord/scale naming can have multiple enharmonic or theoretical interpretations. Reference tones and noise should be used at comfortable playback levels; browser controls do not measure sound-pressure exposure.

Practical guide and verification

Use the tool first, then apply these checks to verify the inputs, interpret the result, and hand it off without displacing the primary workflow.

Set the tuning before reading any pattern

Every fret position depends on the open-string pitches. Standard tuning, Drop D, DADGAD and custom tunings move notes to different frets, so save the tuning with any scale or chord map you export.

Use intervals to understand the pattern

Note names are useful, but scale degrees and chord intervals reveal why a shape functions harmonically and make it easier to move the pattern to another key. Switch between note and degree labels when practicing rather than memorizing only colored dots.

Treat the visualizer as a map, not fingering instruction

A highlighted note can be theoretically part of the scale or chord while being awkward in a particular position. Choose practical fingerings, string changes and position shifts separately, and use a teacher or trusted method when technique matters.

Check enharmonic spelling in context

A pitch class may be written as C# or Db depending on key and harmonic function. A compact browser map may prefer one spelling for readability. Preserve the musical key or chord context if exact theoretical spelling matters in notation or analysis.
