The six strings of a standard guitar are tuned to specific notes, which form the foundation for playing music and understanding the fretboard. Each open string corresponds to a musical note, and as you move up the fretboard, the notes ascend chromatically.
  • The standard tuning for a six-string guitar is: E, A, D, G, B, E.
  • This tuning is used on virtually all standard guitars and is essential for playing most guitar music.
  • Knowing the open string notes helps with tuning, chord formation, and scale practice.

Each String and Its Note

Starting from the lowest-pitched string (thickest) to the highest-pitched string (thinnest), the notes are:
String NumberNoteDescription
6ELowest pitch, thickest string (bass)
5ASecond lowest
4DMiddle of the bass strings
3GHighest of the “bass” strings
2BSecond highest
1EHighest pitch, thinnest string
D
2nd string

Fretboard Note Progression

Notes on each string move chromatically up one half-step per fret. Starting from the open-string note, the sequence for each string is:
  • Open string (fret 0): the string's base note
  • Fret 1: Base note + 1 semitone
  • Fret 2: Base note + 2 semitones
  • ...
  • Fret 12: Base note an octave higher (same note name, 12 semitones up)
For example, the 6th string (E) frets would be:
E (open), F (1), F# (2), G (3), G# (4), A (5), A# (6), B (7), C (8), C# (9), D (10), D# (11), E (12).
A (6th string, 5th fret)
12

String-to-String Relationships

There are specific intervals between adjacent open strings:
  • 6th to 5th string: A (5th interval)
  • 5th to 4th string: A (5th interval)
  • 4th to 3rd string: A (5th interval)
  • 3rd to 2nd string: B (major 3rd interval)
  • 2nd to 1st string: A (5th interval)
This staggered tuning (especially the major 3rd between G and B strings) affects chord shapes and scale patterns.

Conclusion

The guitar’s six strings are tuned E-A-D-G-B-E, from lowest to highest pitch. Each open string corresponds to a specific note, and notes ascend chromatically as you move up the frets. Understanding string notes and intervals is essential for mastering chords, scales, and the entire fretboard.
  • Standard tuning is E-A-D-G-B-E for strings 6 to 1.
  • Notes increase by a half-step with each fret.
  • Intervals between strings shape how chords and scales are played.
