What Dmaj7♯5 is made of

Dmaj7#5 (D major seventh sharp five) is built from the notes D, F#, A#, C#, with the interval pattern 1, 3, #5, 7.

Stack 1, 3, #5 and 7 on a root of D and you get D, F#, A# and C#. That interval recipe is what makes the chord a major seventh sharp five chord — move the same shape to another root and the character travels with it, which is why Cmaj7♯5 sounds like a transposed Dmaj7♯5.

Spelling: the notes above are written the way a score would write them, not simplified to the nearest piano key. That is why this chord is spelled with F♯ rather than its enharmonic equivalent.
