The founder story

Built by a musician. For musicians.

From making beats in a bedroom to helping musicians around the world finally understand how music works.

1. 2010 — It started with a beat.

   I began making beats and creating YouTube tutorials with no musical background. I loved making music, but soon realized how much I didn't understand.

2. 2015 — Musiciangoods was born.

   I started building tools to make music theory easier — for myself and others. That grew into Musiciangoods, a music education brand.

3. The Simplified book series.

   I wrote the Music Theory Simplified series for piano, guitar, bass, ukulele and violin.

4. The next step: PlayTheory.

   I realized that reading about theory isn't enough. You need to play it, hear it, and get instant feedback. PlayTheory brings everything together — the way I always wished I could learn.

“Music theory shouldn't just be something you learn. It should be something you play.”

• The keyboard becomes your teacher.

  You play the notes yourself and hear straight away whether they are right, so you can tell where you went wrong.

• You understand what you're playing.

  Lessons show why chords belong together, so you start to notice the patterns in songs you already know.

• No more "what now?"

  A practice session is laid out for you every day, sized to the time you have, even when that is ten minutes.

• Intervals make sense off the page.

  You see them on the keyboard, hear the difference, then find them yourself.

• A reason to come back.

  Practice that fits around work, and any concept can be played again when you have forgotten it, without sitting through a video.

• Hear it for yourself.

  The first lessons are free, and you play from the first step.
