Guitar Note Names Explained (A–G, Sharps & Flats)
Guitar Note Names Explained
Understanding guitar note names is essential for learning the fretboard, building chords, and making sense of music theory. This beginner guide explains the note letters A to G, how sharps and flats work, and how these notes appear on the guitar.
🎸 📋 The musical note letters (A–G)
Western music uses only seven note letters:
A – B – C – D – E – F – G
After G, the sequence starts again at A. These same seven letters repeat across the entire guitar fretboard.
🎸 🎼 What are sharps (♯) and flats (♭)?
Between most note letters, there is a note in between called a sharp or flat. These are the same sound, just named differently.
- Sharp (♯): one fret higher
- Flat (♭): one fret lower
Example:
- G♯ = one fret higher than G
- A♭ = one fret lower than A
G♯ and A♭ are the same note on the guitar — just named differently.
🎸 ❗ Important rule: no sharps or flats between B–C and E–F
There are no sharps or flats between:
- B → C
- E → F
This means B goes straight to C, and E goes straight to F on the fretboard. This rule explains many fretboard patterns.
🎼 All 12 Notes Used on the Guitar
Although there are only seven letters, guitar music uses 12 repeating notes:
A – A♯/B♭ – B – C – C♯/D♭ – D – D♯/E♭ – E – F – F♯/G♭ – G – G♯/A♭
After these 12 notes, the pattern repeats at a higher pitch.
🎸 📋 How note names appear on the guitar fretboard
On the guitar:
- Each fret moves up by one note
- Notes repeat every 12 frets
- The same note appears in multiple places

🎸 🔁 Note names + octaves
When you move up 12 frets, you reach the same note name again — this is an octave.
Example:
- A string, 3rd fret = C
- A string, 15th fret = C (octave)
