About this item

For the musician who can’t just let it slide when someone calls it F instead of E#, this shirt gets it. It’s Not F, It’s E# is a clean academic music theory tee built around one of the most satisfying forms of musician humor: enharmonic spelling.

Designed for music teachers, theory students, composers, pianists, choir nerds, and anyone who has ever said “technically…” in rehearsal, this shirt combines a bold typographic layout with a notation-inspired music theory joke. It’s perfect for lessons, rehearsals, music school, recitals, and gifting to the musician who always notices enharmonic spelling.

Perfect for:

  • music theory teachers and students
  • composers, arrangers, and notation nerds
  • pianists, accompanists, and choir directors
  • AP Music Theory students and classical musicians
  • anyone who enjoys music theory jokes about enharmonic spelling

– Each item is made specifically for the customer who ordered it
– Allows us to offer a wider range of designs, sizes, and colors without maintaining large inventories

– Colors may appear slightly different depending on your screen settings.
– Print placement may vary slightly between sizes and garments.
– Small differences between mockup images and the finished product are a normal part of made-to-order printing.
