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.

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.
