What’s on the The Harmonic Series poster
A definition and 6 facts worth remembering.
A vibrating string or column of air sounds a fundamental plus a series of quieter overtones at whole-number multiples of its frequency. The mix of those overtones is what makes a violin and a flute sound different on the same note.
- Harmonic 1 is the fundamental — the pitch you name.
- Harmonic 2 is one octave above: exactly double the frequency.
- Harmonic 3 is an octave and a fifth: a 3:2 ratio.
- Harmonic 4 is two octaves; harmonic 5 adds the major third.
- Simple ratios sound consonant; complex ones sound dissonant.
- Brass instruments play the series directly — valves just change which fundamental.
- Octave — 2:1
- Fifth — 3:2
- Major 3rd — 5:4
- Harmonics 4, 5 and 6 are a major triad. It is in the physics before it is in the theory.
The 7th harmonic is flatter than any note on a piano. Equal temperament is a compromise, not a truth.

- Who is the The Harmonic Series poster for?
- The Harmonic Series 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 The Harmonic Series poster?
- Every note you have ever heard is a stack of these. Consonance is not a convention; it is arithmetic. A wall chart earns its place by being glanceable from where the work is happening, so The Harmonic Series belongs on the wall where that music work actually happens, within glancing distance, rather than filed away.
- What other posters go with The Harmonic Series?
- Borrowed Chords, Cadences and Building Chords sit alongside The Harmonic Series 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 The Harmonic Series poster free to download and print?
- Yes. The Harmonic Series 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 The Harmonic Series poster print at?
- The Harmonic Series 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 The Harmonic Series loses nothing.Printing guide
