What is Open A tuning?

Open A tuning is E-A-E-A-C#-E (low to high). Strumming all strings produces an A major chord. It's structurally the same as Open G but one whole step higher.

Is Open A the same as Open G with a capo?

Yes, musically they are identical — Open G with a capo at fret 2 gives you the same pitches as Open A. Many players use this approach. Without a capo, Open A has higher string tension which some slide players prefer for better control.

What scales work in Open A?

The A major pentatonic and A blues scale are natural choices. A Mixolydian gives a bluesy feel, and the A major scale works for country and folk styles.

Sol Locria #2 en Open A — Notas e Intervalos

La escala Locria #2 de G es una versión más usable del modo Locrio estándar. En Guitar, las notas son G, A, Bb, C, Db, Eb, F. Es la opción preferida en jazz para improvisar sobre acordes semidisminuidos — esa segunda natural permite una conducción de voces mucho más suave y melódica que el Locrio puro. Usada comúnmente en Jazz, Post-Bop, Contemporary. Entre los intérpretes destacados se encuentran John Coltrane, Woody Shaw, Steve Coleman. Use over m7b5 chords. The preferred jazz choice over half-diminished chords (vs standard Locrian which sounds too harsh).

Acerca de la Afinación Open A

Open A tuning (E-A-E-A-C#-E) produces an A major chord when strummed open. It is structurally identical to Open G tuned up one whole step, delivering a brighter, more tense sound that works particularly well for slide guitar centered on the key of A.

Jimmy Page used Open A with a slide on Led Zeppelin's 'In My Time of Dying' from Physical Graffiti (1975). Rory Gallagher also employed Open A for his raw, energetic slide work. Many players achieve Open A by simply placing a capo at the 2nd fret in Open G tuning, which is why dedicated Open A usage is less commonly discussed. However, without a capo, Open A gives direct access to the open A string resonance and a different feel under the fingers due to the higher tension.

The natural 2nd degree (vs b2 in standard Locrian) makes this vastly more usable — smoother voice leading while retaining the essential b5 for half-diminished harmony.
