\n

The Twelve Assistant chord chart library gathers a collection of ready-to-play charts organized by genre: blues, jazz, pop-rock and French classics. Instead of starting from scratch, you browse real song charts, listen to them, and add them to your music stand in one click. Each chart comes with its key, its section structure and a short teaching note that explains what is happening harmonically. It is the ideal place to find a solid starting point, understand how a standard is built, or assemble a repertoire to practice. Once added, the chart becomes fully editable in the editor, ready to place on your sheets and export to PDF.<\/p>\n<\/div>\n

Key features<\/h2>\n

The library is designed to move quickly from the catalog to the song you want to play.<\/p>\n

Feature 1: charts organized by genre<\/h3>\n

Charts are organized by musical genre, from blues to jazz through pop-rock and French classics. You browse each family and spot at a glance the style you are after, with a real preview of the chart before you even open it.<\/p>\n

Feature 2: search by title or artist<\/h3>\n

A search field filters the library by song title or by artist. You quickly find a specific standard or explore what exists around a name, without scrolling the whole list.<\/p>\n

Feature 3: key, structure and teaching note<\/h3>\n

Each chart shows its key and scale on the card, along with its section structure. A teaching note accompanies the chart to explain its harmonic logic, making it a real learning resource and not just a chord sequence.<\/p>\n

Feature 4: add to music stand in one click<\/h3>\n

The Add to my music stand button copies the chart into your workspace, ready to place on a sheet or reopen in the editor. You build your own repertoire from the library, song after song.<\/p>\n

Feature 5: listen before you choose<\/h3>\n

You can listen to a chart directly from the library to hear its harmonic color before keeping it. A simple way to compare several charts and keep the one that matches what you are looking for.<\/p>\n

Feature 6: open in the editor with the right key<\/h3>\n

Opening a chart in the editor applies its key, and its scale when recognized unambiguously, to the active layer. You start again in the right harmonic context to customize the chart, transpose it or restructure it.<\/p>\n

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

From discovery to a chart ready to work on, it all fits in a few clicks.<\/p>\n
