Halloween is right around the corner. What are some common chords and scales uses for spooky effect?
@Wasnex: How do you recognize a stack of diminished fourths as diminished fourths and not as a stack of major thirds (or maybe a mix of both)?
.As you might have read, I know the difference.Answering the OP has me a bit out over my skis. Sorry I thought I made that clear.
In regards to your question:
A to Db = Dim 4th
A to C# = Maj 3rd
To the ears these intervals sound the same. The distinction is in how the tones are written.
Enharmonics
A = A
C# = Db
E# = F = Gbb
Quartal: Stacked dim 4ths: A,Db,Gbb
Tertian: Stacked Maj 3rds: A,C#,E#
A,Db,F is also the same sound. You could call this "tertian" Db Augmented in 2nd inversion. The spelling makes sense if considered in root position. Db Augmented = Db,F,A. However A,C#,E# does not sound the same as Db,F,A.
I wouldn't be surprised if it exists in some esoteric 20th century piece. I also wouldn't be surprised if it doesn't. UNSUBYou can try to give an example as a proof, but I doubt you can find one. Even two adjacent diminished fourths melodically are hard if not impossible to find or construct.
While playing, too! As Prof. Kasper and others suggest, above, think big, CG! Four-note arps, tritones . . . them's for squares! You want to scare the whole neighborhood, you want segments! Long concatenations of notes; a page of demented licks! No, er, half-measures when seeking a descent into terror!. . . I would leave the lights on while listening...
