Tablight

Light up your tab.

Turn any melody, MIDI or tab into a guitar part you can hear, loop, and play along with.

Free, private, and entirely in your browser — no account, nothing stored. Guitar-first, but it speaks piano and violin too: write a line once and practise it on whichever instrument's in your hands.

• Get your music in — a melody you tap out on the on-screen piano, a MIDI file, or a guitar tab (plain-text or PDF). Whatever you've got
• It becomes a playable guitar tab — Tablight works out the frets in the tuning you choose. What was flat and silent is suddenly under your fingers
• Hear it, loop it, play along — sampled playback, slowed down as much as you like, with your own timing punched in and any passage drilled on a loop that ramps the tempo each lap

• Detects the key and scale of whatever you enter, automatically
• Analyses chord structures and voicings across the fretboard
• Transposes to any key in seconds
• Shows the same notes as piano keys or violin fingerings — with finger numbers, and unreachable notes flagged
• Falling-notes practice on piano, Synthesia-style — taller blocks for longer notes
• Exports as a Tablight file to keep editing, or as plain-text / PDF tab to print or open elsewhere

• Composers sketching and editing their own material
• Musicians analysing the theory behind a piece
• Guitarists checking a transcription they made themselves
• Pianists and violinists who want to see a line under their fingers
• Anyone with a MIDI file they want to see and practise on their own instrument
• Anyone drilling an awkward passage on a loop, at their own tempo
• Anyone who thinks in frets, keys and strings rather than sheet music

Tablight is free and built in spare time.
A coffee is appreciated and keeps the project alive.
