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.

La# Locria #2 en Open A — Notas e Intervalos

La escala Locria #2 de A# es una versión más usable del modo Locrio estándar. En Guitar, las notas son A#, C, C#, D#, E, F#, G#. 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.
