How to transcribe a drum groove by ear

Transcribing a groove is not one hard job. It is four easy ones done in order. You write the hi-hat, then the kick, then the snare, then the ghost notes, and you check each layer against the recording before you add the next. Stop at whichever layer the gig needs.

1. Slow it down and loop one bar

Nobody hears a 16th-note kick pattern at full speed on the first pass. Put the track in anything that slows audio without changing the pitch: YouTube's playback speed, a looper app, or a stem-separation app that can turn the other instruments down. Start around 60 percent. Loop one bar, or two if the groove is a two-bar phrase, and leave it looping while you work.

Pick the cleanest example of the groove in the song. The second verse is usually better than the first: the drummer has settled, and there is less going on than in a chorus.

2. Find the pulse and count the bar

Tap your foot and count out loud: "1 e and a, 2 e and a". If the count fits, the groove lives on a 16th-note grid. If "1 and a" feels more natural, it is in triplets or swung, and you should write it that way from the start rather than forcing it into 16ths.

Find beat one by listening for the crash at the top of a section or for the chord changes. Groove transcriptions go wrong most often by starting on the wrong beat, and every layer after that inherits the mistake.

3. Write the hi-hat or ride first

The cymbal pattern is the grid everything else hangs on, and it is the easiest part to hear. Listen for whether it is 8ths or 16ths, whether any notes are accented, and whether the hat opens anywhere. An open hat sounds longer and washier, and it is usually on an "and".

In a mix the hat is often panned a little to one side. If you are using headphones, try listening with one ear.

4. Add the kick

The kick is the hardest layer to hear, so give it its own pass. Count each kick against the hat you already wrote: "on the 1, then the and of 2, then the and of 3". Turning the bass down helps a lot, because the bass player is usually doubling the kick and the two blur together. If something low sounds like a kick but with pitch, it is probably the floor tom.

5. Add the snare

Write the backbeat first. In most rock, pop, funk and worship grooves that is beats 2 and 4. Then listen for anything else on the snare that is as loud as the backbeat, and add it.

For a lot of songs you can stop here. If you are charting a set for a sub gig, three layers and a bar count is the right amount of detail. See how to write a drum chart for the rest of that page.

6. Add the ghost notes

Ghost notes are the quiet snare strokes between the backbeats. You hear them less as notes and more as a rattle or a shuffle in the groove. Turn the volume up, loop the bar slower still, and listen in the gaps either side of the backbeat. Write them in parentheses so they read as soft.

If you cannot tell whether a ghost note is there, leave it out. A groove with one ghost note missing still grooves. A groove with an extra one you invented often does not.

7. Check it against the recording

Play your bar along with the track at the slowed-down speed, then at full speed. Either play it on a kit or pad, or play back what you wrote if your tool can. Wherever it rubs, the error is almost always in the kick. Fix that bar before you move on.

Then listen through the rest of the section for changes. Drummers rarely play a groove identically sixteen times. Most of the variations are feel, and you can leave them out. Write down only the ones that repeat or that the band locks into.

8. Reduce it to a chart

A transcription is not finished until it fits on one page. Write the groove once with its bar count, and write out only the bars that are different: the fill into the chorus, the stop, the hits. Use the standard notation key so anyone can read it.

How detailed should it be?

As detailed as the job needs, and no more. A sub gig needs the form, the groove and the hits. A lesson or a cover that has to be note-for-note needs every ghost note. The method is the same either way. You stop at a different layer.

That is how Rhythm Writer works too. You paint each layer on a grid, see it as real notation as you go, and hear it back against your ear before you add the next one. A one-box chart or every ghost note, it is fast either way, and it prints as one page you can read at the kit.
