The Twelve Assistant chord chart editor turns a chord sequence into a real, ready-to-play chart you can read, structure and share. Built for guitarists, pianists and teachers, it lets you write a chord chart in international notation (C, Dm, G7) in seconds, then organize it into sections, transpose it and export it to PDF. Whether you are preparing a song for a rehearsal, a worksheet for a student or the harmonic skeleton of a composition, you type your chords or paste an existing sequence, and the chart lays itself out. Integrated with the digital music stand, the tool becomes the starting point of a complete workflow, from the first chord idea to the printed sheet.<\/p>\n<\/div>\n

Key features<\/h2>\n

The editor brings together everything needed to compose, organize and share a chord chart, without leaving the page.<\/p>\n

Feature 1: fast international-notation input<\/h3>\n

Type a chord then press Space to move to the next cell, or paste a full sequence directly. Vertical bars and line breaks automatically create bar breaks. A single slash writes a slash chord (for example D\/F#) and a double slash places several chords in the same bar (D\/\/G shows as D\/G). Writing stays instant, with no intermediate dialog.<\/p>\n

Feature 2: titled sections and recalls<\/h3>\n

Split your chart into named sections (Intro, Verse, Chorus, Solo) and reorder them by drag and drop or with the arrows. You can recall an already written section without redrawing it, which is handy for a song that repeats the same chorus several times. Sections can also be placed at the very start of the chart.<\/p>\n

Feature 3: multiple chords per bar with rhythm<\/h3>\n

A bar can hold several chords in the same row, with an optional rhythm line underneath to show where each chord falls. One character per beat marks the attack or the hold of the chord. This lets you notate a chart where the harmonic rhythm changes within the bar.<\/p>\n

Feature 4: smart transposition<\/h3>\n

Transpose the whole chart in one click: the chords and the key indication at the top update together. The composition bar, which shows degrees I to VII of the active scale, follows the transposition too, without ever changing the mode by mistake. A chart in A blues minor transposed up two tones stays in B blues minor.<\/p>\n

Feature 5: harmonic context menu<\/h3>\n

A right click (or long press) on a chart chord opens a menu that adds it to the music stand, shows its diagram, or overlays it on the active scale on the fretboard. Two advanced entries, overlay with the previous chord and overlay with the next chord, display the fretboard with both chords compared and a color legend to spot common notes and changing notes.<\/p>\n

Feature 6: PDF export and music stand integration<\/h3>\n

The sheet is A4, aligned with the music stand, with automatic pagination, a logo at the top and a copyright note at the bottom. The PDF export stays clear, sheet-music style, even in dark mode. The add to stand button files the chart in your workspace, where you then drag it onto a sheet with an adjustable width.<\/p>\n

How to use the tool<\/h2>\n

Creating a chart takes seconds, structuring and exporting it barely longer.<\/p>\n

    \n
  1. Open the chord chart editor from the home page or the search bar.<\/li>\n
  2. Choose or confirm your key, then type your chords separating bars with a vertical bar, or paste an existing sequence.<\/li>\n
  3. Add named sections and reorder them to match the song structure.<\/li>\n
  4. Fine-tune multiple chords and the rhythm line inside a bar if needed.<\/li>\n
  5. Transpose to the desired key, then export to PDF or add the chart to the music stand.<\/li>\n<\/ol>\n

    Concrete example: to prepare a blues in A, type A7 | D7 | A7 | A7 | D7 | D7 | A7 | A7 | E7 | D7 | A7 | E7, add a 12-bar section, transpose to C if your singer asks, and export the sheet for the evening rehearsal.<\/p>\n
