    Default Warping a track that changes time signatures

    I'm trying to warp a track that starts off(if i remember correctly) in 6/8 slow and half way goes into 3/4 then back into 6/8. I'd put the avg tempo at around 90 bpm. I want to get it to sound decent in 4/4 at around 175 - 180 dnb. I was wondering if anyone had any ideas on how to do this before i go crazy from trial and error testing. The track is Sondheim - The Ballad of Sweeny Todd - Original Cast Recording. I don't know where my sheet music is for the show, so time signatures are from memory so they may not be accurate, but i do remember alot of signature changes from when i did the show many years ago. cheers

    3/4 and 6/8 are the same thing surely*

    When you say you want it to sound decent in 175-180 do you mean using 3 against 4 so each bar of 4/4 at 180 would be a complete bar of 6/3/3/4? If so you'll need to get the slower track to about 120 bpm ie 180 / 1.5


    *well technically not, 6/8 is usually grouped (1)23 (2)23 xxxxxx. in quavers 3/4 would be 1x 2 x 3 x, but in terms of quavers per crotchet, if you know what i mean.

    No, they are. 3/4 is the simple version, and 6/8 is the complex version of the same musical sound - beats arranged in triplets. The difference is that in a measure of 6/8 there are 2 downbeats per measure and in 3/4 there are 3. But in both, the musical idea of triplets is the reason those time signatures are used.

    ...6/3/3/4...
    WHAT? No sir. What are you trying to convey here, because that isn't a time signature. Even if you're trying to convey an additive time signature, it's not written correctly and makes no sense.

    Well put - that's what i was trying to convey. For example - take i want to be in America - Alternating bars of compound <pedant>(not complex)</pedant> time - 6/8 and simple time - 3/4

    6/8 I want to be in A 3/4 Mer-i-ca

    The underlying crotchet pulse remains the same although the stresses (and thus percieved pulse) of the downbeats changes. Although they feel like triplets they're not usually written as such in 6/8 time. (ie with the 3 marker across the top).

    WHAT? No sir. What are you trying to convey here, because that isn't a time signature. Even if you're trying to convey an additive time signature, it's not written correctly and makes no sense.
    That's a typo - 6/3 / 3/4 was meant to be "(6/8) / (or) (3/4)".

    I'll paraphrase the sentence.

    "When you say you want it to sound decent in 175-180 do you mean using 3 against 4 so each bar of 4/4 at 180 would be a complete bar of 6/3/3/4? If so you'll need to get the slower track to about 120 bpm ie 180 / 1.5"

    translation into english:

    If you want to have a single bar where the time span of a bar in 3/4 and a bar of 4/4 are the same duration, then you need to divide the tempo of the bar in 4/4 by 1.5 in order to get the destination tempo of the bar in 3/4 (6/8).



    Rest of DJTT: (YAWN!)

    Gah! I'm having flashbacks of undergrad. Thanks a bunch, I'll take a look again. And bento, i'll send it over in a bit. I just have a rehearsal CD right now so i gotta borrow the soundtrack from a buddy to do this. Cheers
