  • Stretching the Beat

    February 27th, 2020
    contra, jammer, music  [html]
    Initially when I started playing around with having my rhythm setup subdivide the beat I went with a very simple division of four equal pieces. This works well for some things, but it is also a very rigid sound. When I'm playing on the mandolin I often stretch the beat a bit, pulling subbeats earlier and pushing others later. This is something I learned to do by ear; I just play it.

    But what am I actually doing? I took a recording of myself playing mandolin and measured exactly how far through the beat each of the four subbeats fell. I measured three repetitions worth:

    1 0.000 0.000 0.000
    2 0.154 0.139 0.168
    3 0.275 0.253 0.264
    4 0.444 0.421 0.420
    1 0.574 0.535 0.549

    Converting these into percentages, and calculating an average:

    1 00.0% 00.0% 00.0% 00.0%
    2 26.9% 26.0% 30.6% 27.8%
    3 47.9% 47.3% 48.1% 47.8%
    4 77.4% 78.7% 76.5% 77.5%

    Here's another way of looking at it:

    strict stretched delta
    2 25.0% 27.8% 11% late
    3 50.0% 47.8% 9% early
    4 75.0% 77.5% 10% late

    Here's a video walking through how this sounds and how it fits into the rest of my setup:
