Play along

A song on this page is a progression — an order of chords — looped against the click. Progressions are not copyrightable; only melodies and lyrics are. No melody, no words. Beginner loops stay at four beats. Intermediate adds barre and 12-bar. Advanced cuts the beats, adds 7ths, and mutes on purpose.

Same idea as Piano · Chord changes, with guitar shapes instead of keyboard voicings. Capo if you need to match a singer’s Sa. Roman numerals come from the circle and Open Music Theory: I is the home chord of the key. Want drums + bass + piano under you? Tools · Backing band (minus guitar).

Player

Four-chord song

I – V – vi – IV in G · G · D · Em · C

Beats per chord

Start the metronome for a click; the player also follows that tempo when the metro is running.

Loops

Classical and fingerstyle

First-pieces maps (titles and harmony, no printed tunes or riffs) live on Folk, Classical (and concert-hall names), Rock, Metal, and Solo. This page keeps two public-domain / original doorways so classical / fingerstyle also appear as harmony loops:

Open-string study in Em — thumb on the beat, i–m on the treble strings. Pachelbel’s Canon (1694, IMSLP) is the famous I–V–vi chain; we do not print his melody. Play the Em campfire loop, then take the same right hand to Classical drills.
Thumb + brush on Ghar — folk fingerstyle seed. Same G–C–D–G map, thumb takes the bass, fingers brush the top. Build it on Folk drills.

Carcassi, Sor, and Giuliani (IMSLP) are the trusted spines when you want a named study. Do not copy a numbered exercise onto this page.
