Creating Cross Rhythms to Lock Up Timing
|By AMIR SAID (SA’ID)|
In The BeatTips Manual, in the section on timestretch, I discuss why I don’t rely on timestretch as much as I do on rhythm matching and contrasting. One of the biggest problems dealing with any sampled phrase of 2-bars or longer is the tempo change. Let’s remember, when you sample a song, you’re usually sampling a group of live musicians that played in real time when they recorded the song. As such, the tempo ebbs and flows. Humans are not machines, so natural timing moves slightly. Thus, a song moving at let’s say 90 BPMs (Beats Per Minute) may actually move between 89.7 – 90.3 BPMs over a measure of four bars or more. So the shorter the sequence, the tighter the BPM will be. Conversely, the longer the sequence, the more the BPM is likely to move slightly up or down. All told, tempo change within a sample creates a sequencing and arrangement challenge, especially when it comes to building drum patterns.
There’s No Rule in Beatmaking that Says You Have to Use Timestretch: Rhythm Blending
Whether you like to call it rhythm blending (as I do), beat matching, or beat blending, the concept is all the same: combining/blending/mixing two or more rhythms to make one new rhythmic structure or sound wall. So instead of relying solely on timestretch to solve the arrangement and timing problems that can arise from tempo changes within a sample, utilize creative rhythm structures to achieve similar and often even better (more natural sounding) results.
BeatTip: Work on developing an ear for picking sounds, rhythms, or even melodies that go together or contrast nicely. This is better than forcing sounds and rhythms to fit simply because you have an idea (inclination) and the power of timestretch. Every idea that you have is not supposed to work. And if you’re not careful, timestretch can become a means for forcing some ideas that might have been better left alone.
In the song below, I use a 4-bar phrase that pounds on the initial hit (start of the sequence) then dips and rises three times before it gets to the loop point then loops over again. Instead of using timestretch to manage the shifts in tempo, I used three different hats—in three distinct ways—to shuffle and drag the flow of the beat and to keep the rhythm steady. I used a kick-drum scheme (six tumbling kick-hits) that seems to go against the flow. Finally, I used a straight forward snare on the “2”, which I heavily syncopated near the end of the fourth bar in anticipation of the entire four-bar structure starting (looping) from the beginning. Collectively, I used all of the drumwork to create cross rhythms and a contrast structure that masks the primary sample’s tempo and pitch changes.
