Chord charts, lead sheets and Nashville numbers

Every band has a folder of charts, and every band has 3 versions of the same song in that folder, none of which match what you actually play. The dep gets the 2019 version, plays the outro twice, and the drummer glares at him for the rest of the set.

A chart is a contract between the people on stage. Its job is to answer questions fast, in the dark, at 130 bpm. Here is what works.

Three formats and when to use each

Chord chart (lyrics with chords above): the default for cover bands. Fast to write, readable by anyone, and singers can use it too. Its weakness is form: a lyric chart does not tell you how many bars the intro is or where the stop is.

Lead sheet (melody on a stave, chords above, lyrics below): the standard in jazz and function work, and what you hand to a horn player or a reading pianist. Slower to write unless you use notation software. Necessary when the melody is played by an instrument, not sung.

Nashville number chart (numbers instead of chord names, bars explicitly shown): the professional session and church format. Key-independent, so the same chart works when you move the song for a different singer. Shows form precisely. Requires everyone to be fluent, and a lot of guitarists are not.

A working compromise many bands use: a bar-chart with chord names, one line per section, 4 bars per line, section labels on the left, plus a lyric cue at the start of each section. It has the form clarity of a number chart and the readability of a chord chart.

What every chart must contain

Whatever the format, the top of the page carries the same 6 items:

1. Title and original artist
2. Key (concert key; note if a singer's version differs, see choosing keys)
3. Tempo in bpm and feel (for example "112, half-time shuffle")
4. Form summary: "Intro 4 / V / V / C / V / C / Solo (C) / Bridge / C x2 / Out 2"
5. Count-in and who starts ("drums 4, band on 1" or "guitar riff alone x2")
6. Ending ("hit on 1, ring", "repeat and fade: cue from singer", "cold stop after 'tonight'")

If a chart has the chords right but is missing item 5 or 6, it will still cause a train wreck. Starts and stops are where bands fall apart, not the middle of a verse.

Nashville numbers in 5 minutes

The key is 1. Every chord is its scale degree: in G, G is 1, C is 4, D is 5, Em is 6- (minor is a dash or "m"). One number per bar by default. Two chords in a bar are underlined together or written as "1 4" with a line under them. A diamond around a number means hold; a "<" or ">" or a carat marks a push (the chord lands on the "and" of 4 before the bar).

A chorus of a 4-chord pop song in any key becomes:

1 5 6- 4 | 1 5 6- 4

Move the song from G to Bb for the new singer and the chart does not change. That is the whole selling point. The cost is 30 minutes of practice for anyone who has only ever read chord names, and a small mental tax on the first few gigs.

Bands that do a lot of dep work or move keys often should switch. Bands with one stable line-up and fixed keys usually do not need to.

Writing charts that survive the stage

• One page per song wherever possible. A page turn during a chorus costs a bar. If it will not fit, print 2 pages side by side, never front and back.
• Font size 14 minimum for chords, 12 for lyrics, bigger if the band is over 40. Stage light is bad and glasses come off when sweating.
• Repeats need a count: "x4" not "repeat". Nobody counts repeats the same way.
• Cues in bold: "STOP", "drums only", "band in", "big ending".
• No version ambiguity: put a date or version number in the footer ("v3, Mar 2026"). When you change the arrangement, the old chart gets deleted, not kept "just in case".
• The lyric cue is enough: a full lyric sheet for the guitarist is noise. First 3 words of each section will do.

One chart, one source of truth

The problem is rarely writing charts. It is knowing which chart is current. The pattern that works:

• Charts live in one shared place, one file per song, filenames like superstition-eb-v3.pdf.
• The band leader (or one nominated person) owns edits. Others send corrections; they do not upload their own versions.
• When an arrangement changes at rehearsal, the chart is updated within 48 hours, and the change is announced in one line: "Valerie: outro now x2, chart updated."
• Deps get the link to the folder, not an email with attachments, so they always pull the current file. This is most of what a good dep system is.

Tablet users (forScore, Mobilesheets, a plain PDF reader) should download from the same source. Paper users print from the same source. The moment someone keeps "their own" annotated version, you have forked the arrangement.

Printing for the gig

Print on 80 gsm or heavier paper, single-sided, in setlist order, with the setlist as page 1. Put the pages in a display book or on a clip so wind and spilt drinks do not take them. Tablets need a stand, a charger, and screen brightness at maximum with auto-lock off. Both need a backup: a paper set in the van for the tablet band, a phone with the PDFs for the paper band. More on this in printing setlists for the stage.

Do this today

1. Pick one format for the band and write it down. Mixed formats across the folder are worse than any single format.
2. Take the 5 songs the band most often gets wrong and rewrite their charts with the 6 header items, especially count-in and ending.
3. Delete every duplicate chart in your shared folder. If you cannot tell which is current, play the song at rehearsal and find out.
4. Add a version footer to the template.

Where expert.band helps

Each song in the expert.band repertoire can carry its key, notes and attached chart files, stored in EU data centres, so there is one current chart per song rather than 5 across 3 phones. Members open the same song from their own login, and a dep invited by link sees the same version the band plays. Build the setlist from the repertoire and the charts follow the order you will play them in.
