How to Tune to DADAC#E Tuning

An open D-flavored emo tuning (D-A-D-A-C#-E) that rings out lush, ambiguous voicings for twinkling fingerstyle. The low D-A-D-A stacks fourths and fifths for a droning foundation, while the C# and E on top add color that hovers between major and suspended. American Football, Weatherday and even Radiohead have used this shape.

Start in standard tuning (E-A-D-G-B-E) and change 3 of 6 strings:

Fun Fact

American Football's self-titled 1999 debut turned intricate alternate-tuned guitar interplay into the blueprint for a whole genre. Tunings like this one — where two guitars weave overlapping arpeggios in the same open shape — create the interlocking, mathy texture that defines emo revival.

String Tension & Setup Tips

Recommended Gauge:Light gauges (.010-.046 electric). The low E drops to D and the top strings shift down slightly; overall tension is a touch below standard, keeping the many open strings loose and ringing.

Frequently Asked Questions

What tuning does American Football use?
American Football used several open and modal tunings; DADAC#E is one of their signature shapes. It sets up the interlocking, twinkling arpeggios that made their debut album so influential in emo and math rock.
How do I tune to DADAC#E?
From standard: drop the low E to D, keep A and D, raise the G a whole step to A, raise the B a whole step to C#, and keep the high E. Use the tuner above to set D-A-D-A-C#-E exactly.
Is DADAC#E related to Open D?
Yes. Open D is D-A-D-F#-A-D; this tuning shares the D-A-D bottom but rearranges the upper strings to A, C# and E, giving a more suspended, open-ended color favored in emo and indie rather than slide blues.
