- Who is the Extended Chords poster for?
- Extended Chords belongs to the Music section rather than to a school year, because music is not something one grade owns. Anyone learning theory can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Extended Chords poster?
- Extensions are colour, not structure. Drop the fifth before you drop the third or the seventh. A wall chart earns its place by being glanceable from where the work is happening, so Extended Chords belongs on the wall where that music work actually happens, within glancing distance, rather than filed away.
- What other posters go with Extended Chords?
- Borrowed Chords, Cadences and Building Chords sit alongside Extended Chords in the Music section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Borrowed ChordsCadencesBuilding Chords
- Is the Extended Chords poster free to download and print?
- Yes. Extended Chords downloads as a free PDF with no account, no email and no watermark, like everything else in the Music section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Extended Chords poster print at?
- Extended Chords is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Extended Chords loses nothing.Printing guide
