How to pitch a sample
Gazillion Industries ·
In 2003 a sped-up Chaka Khan hook turned into "Through the Wire,"
and a whole era of soul samples started coming back an octave brighter and twice as
urgent. Pitch is the fastest way to make somebody else's record sound like yours.
To pitch a sample, first find its key, then decide how you want it to move. Repitch
it (change speed and pitch together) for a vintage, record-like sound, or pitch shift it
(keep the tempo) when the timing has to stay locked. Transpose it into the key of your
track in semitones, fine-tune with cents, pitch individual chops separately if needed,
and automate pitch for bends and drops.
The short version
- Find the key
- tuner or key detection, then confirm by ear
- Repitch
- speed and pitch together; sounds like a record
- Pitch shift
- pitch only; tempo stays locked
- Transpose
- semitones to the key, cents to fine-tune
- Chops
- pitch each one to fit the chord
- Movement
- automate pitch for bends and drops
Find the key first
Load the sample, find a sustained note or chord, and check it with a tuner or your
DAW's key detection. Confirm by ear: play the root note on a keyboard under the sample
and listen for the note that sounds like home. Old records often sit a few cents off
standard tuning because of tape and turntable speed, so expect to fine-tune after you
transpose.
Repitch or pitch shift
Repitching changes speed and pitch together, the way a sampler or a turntable does.
Pitch up and the sample gets faster and brighter; pitch down and it slows and darkens. It
keeps the sample sounding like a record, with no artifacts, but it changes the tempo.
Pitch shifting keeps the tempo and moves only the pitch, which fits a sample to a fixed
grid but can sound processed on big moves. More in what is varispeed and how to change pitch without changing
tempo.
How to pitch a sample
- Find the sample's key with a tuner or key detection, then confirm by ear.
- Work out the semitone distance to your track's key.
- Choose repitch for character or pitch shift for locked timing.
- Transpose by that many semitones, then fine-tune in cents.
- If you repitched, adjust your tempo to the sample, or stretch the sample to the tempo.
- Check the sample against your drums and bass, and fix any chop that clashes.
SKRUU
lets you play pitch and time on separate knobs, with shifts that spring back.
Pitch the chops, not just the loop
Chopped samples don't have to stay in their original key. Pitch each chop to fit the
chord under it and a single phrase becomes a melody. Keep an eye on the tone: chops pitched
far up get thin and chipmunky, and chops pitched far down get muddy and slow. If a chop
thins out, see how to make a
sample sound fuller.
Automate pitch for movement
A pitch drop at the end of a phrase, a slow bend into a hook, a sample that sinks as
the beat drops out: automating pitch turns a static loop into a performance. With repitch,
the speed moves too, which is what gives a slow-down its weight.
Questions people ask
How do I change the pitch of a sample without changing the tempo?
Use your DAW's pitch shifting or a stretch mode that keeps the tempo locked, then
transpose the sample in semitones. Small shifts sound most natural.
Should I pitch samples up or down?
Either, depending on the feel. Pitching up makes a sample brighter and more urgent;
pitching down makes it darker and heavier. Keep it in the key of your track, and watch the
tone at larger shifts.
How do I find the key of a sample?
Check a sustained note or chord with a tuner or key detection, then confirm by playing
root notes under it until one sounds resolved. Expect to fine-tune a few cents on old
records.

What SKRUU does
SKRUU is our varispeed pitch and time stretch plugin for drums and samples.
PITCH runs from −20% to +10% and reads out in semitones as well as speed,
so you know exactly how far off the record you are; the display compares what went in
against what came out. TIME moves the length on its own knob, and
ELASTIC springs either one back along one of sixteen shapes, from a smooth
glide to a ratchet. Four sampling grades, down to 3.91 kHz, add a staircase when you
want grit.
Twenty-odd years later, the soul samples still come back brighter. Now you know
how.
