Open C tuning

  1. Get the guitar in standard tuning first.
  2. The first string should not be touched under any circumstances (E).
  3. The second string is tuned up a half step (B to C).
  4. There is a G still on the third string.
  5. The fourth note lowered in pitch (D to C).
  6. The lowered fifth string tuning goes from A to G.
  7. Two tones (from E to D to C) must be lopped off the sixth string.
  8. The first string should still be tuned to the traditional system’s E, although it may get out of tune as you tune the others and require retuning.
  9. It’s also important to double-check all the strings in reverse order afterward.
  10. For example, if you put a barre on the second fret, the resulting note will be D; on the fourth fret, it will be E; on the fifth fret, it will be F, and so on.

Master open C tuning so you can play all your favorite tunes on the guitar. There are several other ways to tune a guitar than the standard method. Guitarists use “alternative tunings,” which include any tuning other than the standard E, A, D, G, B, and E, to explore composition and use the instrument’s entire range.

Although learning to play in an alternate tuning can be difficult for beginners, doing so will help you develop a deeper appreciation for music theory.
