#010 - Tune Your Kick to the Song Key

Most producers select a kick by feel and leave its pitch wherever the sample was recorded. The result: the kick fundamental sits at some random pitch that creates dissonance with the bass and sub when they hit together. Tuning the kick so its fundamental aligns with the tonic of the song key makes kick and bass feel like a single musical element rather than two competing voices in the low frequencies.

The technique

1. Identify the key of your song (e.g. F minor → tonic note is F)
2. Solo your kick and use a spectrum analyser to find its fundamental frequency (the lowest dominant peak)
3. Convert that frequency to a note - there are free pitch-to-frequency charts online, or use a tuner plugin
4. If the kick fundamental isn't your tonic (F, in this example) or a perfect fifth above it (C), pitch the kick up or down in semitones until it is
5. Verify with the bass playing - the two should feel locked rather than fighting

This is a 30-second move that delivers disproportionate improvement to mix coherence. Particularly noticeable in DnB and dubstep where the kick and sub bass are interlocked rhythmically and tonally for the entire track. Once you start doing this, untuned kicks against tuned basses sound obviously wrong.
