Bluegrass runs on chord charts, not sheet music. A chord chart doesn’t tell you which notes to play — it tells you which chord to be on, and for how long. That’s all a rhythm player needs, and it’s enough to follow almost any tune at a jam. Learn to read one and you can sit down with a chart you’ve never seen and play along.
The grid: each box is one measure
A chord chart is a grid of boxes. Each box is one measure (also called a bar) — a small, equal chunk of time. The chord written in a box is what you play for that whole measure. You read the boxes the way you read words on a page: left to right, top to bottom.
So a row that reads G G C G means: play a G for one measure, another G for a measure, a C for a measure, then a G for a measure — four measures, in order. When you reach the end of a row, you drop to the start of the next row and keep going.
Reading the chords themselves
A chord name has two parts: the root (a letter, A through G, sometimes with a sharp # or flat b) and the quality (a small suffix). A bare letter like G means a major chord. A small m — as in Em — means minor. You’ll also see 7 (a dominant seventh, like D7) and occasionally others, but the vast majority of traditional tunes use plain major and minor chords.
Sometimes you’ll see a slash, like G/B. That means “play a G chord, but with a B in the bass” — the note after the slash is the bass note. It’s common under a bass run or walk-down.
Sections and repeats
Tunes are built from sections — often labeled like A Part and B Part for fiddle tunes, or Verse and Chorus for songs. Each section is its own little grid of measures. Grouping the chart this way makes a long tune easy to follow, because you’re really only tracking a handful of short sections.
A repeat tells you to play a section more than once before moving on. A section marked ×2 is played through twice. In old-time and bluegrass, playing each part twice (AABB) is the norm for fiddle tunes, so repeats show up constantly.
- A Part ×2, then B Part ×2 = the classic AABB fiddle-tune form.
- Verse then Chorus, alternating = the classic song form.
- The arrangement is the order you play the sections in — the roadmap for the whole tune.
The whole thing is a chord chart
Every song page on this site is a chord chart, laid out exactly this way — a grid of measures grouped into parts, with the chords spelled out. The best way to learn to read one is to read one while it plays. Open any tune, watch the chart, and follow the boxes as the band moves through them.
Watch the chart below the player highlight each measure as the band plays through the A and B parts.

Start with tunes that have simple, repeating shapes so the reading is easy and you can focus on the pattern. The easy bluegrass songs are ideal — two or three chords, clear parts. Then move to the fiddle tunes, where you’ll get comfortable with the AABB form and quicker changes. Read the chart, play along with the band, and it becomes second nature fast.
