Every trebly poster is a starting point. Change as much or as little as you like: the Poster Maker lays it out for you and keeps every word readable.
Four styles and dozens of colors
Trebly, Minimal, Dark or Modern, each with its own background colors: cream, sky, sage, midnight, navy, forest, burgundy and more. Here's the same Reading & Rhythm poster in all four.
Pick from 70 sections
Note names, rhythms, time signatures, key signatures, the circle of fifths, scales, piano fingering, guitar and bass chords, dynamics and more. Tick the ones you teach, put them in order, and make one or two featured so they stand out.

Your own words
Your studio or school name as the title, a subtitle, your own practice tips, a favorite quote or a message, and a personal note along the bottom.
Readable from across the room
The Poster Maker checks the text size for the paper you choose, keeps it big enough to read on the wall, and suggests a bigger size or fewer sections when a poster gets crowded. You see exactly what you'll print.

Questions
Is the Poster Maker free?
Trying it is: change anything and see the result. Ready-made posters stay free to download, in any size and with US or UK terms. A poster you've changed is a $9 PDF.
What size should I choose?
Letter or A4 for a home printer; A3, 11 × 17 in or bigger for a classroom wall. The Poster Maker tells you if the text would be small at the size you picked.
Can I print it at a print shop?
Yes. Ask for it at 100% (actual size) on your poster's paper size, with no trimming. For color right to the edge of a colored poster, our printing guide explains what to ask for.
Can I use it in my classroom or school?
Yes: print as many copies as you like for your home, studio, classroom or whole school, and hand them to your students. Please don't sell it or share the file online. See the poster terms.
Can I come back to my design later?
Yes. “Copy save link” keeps the whole design in a link, with no account. Open it on any device to carry on.
What if I spot a mistake after buying?
You can fix it once for free within 30 days, from the link in your email. The corrected PDF replaces the first.
Can't I just make one in Canva or Word?
You can lay out text and boxes, but you'd have to draw the music yourself (staffs, notes, key signatures, chord boxes) and check every note. The Poster Maker draws the music from checked content and keeps the text readable at your size.
Can I add a photo or logo?
Not yet. It's on our list.
Can I get a refund?
You see your exact poster before you buy, so we don't refund a change of mind. If something's wrong with your PDF, email support@trebly.fun and we'll fix it or refund you.
