have just the E string dropped to D. The other 5 are standard tuning.
The chord is an A with C# note(3rd finger 5th string 4th fret). With an open D string it sounds interesting. Then put 3rd finger on 6th string 4th fret, pinky 5th string 4th fret for 2nd chord, while barring A chord with first finger. As far as I can tell, the 2nd chord is really an F#minor.
