Fretwise

Chapter 1

Getting Started

What music theory actually is, why guitarists need it, and the absolute essentials — notes, the alphabet, half- and whole-steps — that everything else builds on.

Music theory is just the names we give to things we can already hear. It’s not magic, and it’s not a barrier — it’s a shared language that makes the patterns of music visible.

This chapter gives you the four things you need before anything else makes sense: the musical alphabet, the idea of a half-step, what a “key” roughly means, and how the guitar fretboard maps to all of it. By the end you’ll be able to name any note on any string.

If you’ve never read theory before, work through every lesson in order. If you’re returning after a break, you can skim — but don’t skip the half-step lesson; it’s the seed of everything in this book.

Lessons in this chapter

  1. 1 What music theory is (and isn't) A short, honest definition of music theory and why it makes you a better guitarist.
  2. 2 The musical alphabet & half-steps Music uses only 12 notes. Learn their names, why some have sharps and flats, and how they sit on the guitar.
  3. 3 Fretboard anatomy & standard tuning Strings, frets, the nut, dot inlays — and the standard tuning that makes the guitar's logic work.
  4. 4 Octaves & how pitch works What an octave really is, why two notes one octave apart sound "the same", and the octave shapes that map the whole fretboard.
  5. 5 What is a "key"? A working definition of "key" before we dive into scales and chords — the most useful idea in music.
