From Loop to Finished Track: A Music Production Lesson

A loop becomes a finished track when you decide its length before adding anything, lay the loop across that whole length, and then take parts away so that each section sounds different from the one before it. Every border between sections then gets a transition, and the track is done when it exists as an exported audio file with a date on it. This lesson does that with one eight-bar loop, bar by bar, until it is a three-minute track, and the steps work the same in any DAW, the digital audio workstation where tracks are built.

Why a Good Loop Stalls

Many unfinished projects stall at the same point: eight bars that sound good on repeat and nothing after them. The loop sounds good because every part is playing, which makes it the chorus already. Adding a ninth or tenth layer to it makes the chorus denser and leaves the rest of the song unwritten, which is why a producer can spend a month on a loop and still have eight bars.

A song gets its shape from contrast between sections, and contrast comes mostly from what is missing. A verse feels like a verse because the chorus parts are not in it yet, and a chorus lands because something was held back before it. So the work of arranging is mostly deciding what to remove, where, and for how long.

Length comes first because contrast needs a frame. In 4/4 time, the meter of most pop, hip-hop and electronic music, one bar lasts 240 divided by the tempo, in seconds. At 96 beats per minute a bar is exactly 2.5 seconds, eight bars take 20 seconds, and a three-minute track is 72 bars. That arithmetic is why this lesson uses 96. At another tempo the bar count changes and the method does not.

The Starter Loop

The project starts from an eight-bar loop in A minor at 96 beats per minute. If you built the four-lesson loop in our guide to music production lessons for beginners, yours has most of these parts already and can stand in for this one. Set that project from 90 to 96 beats per minute so the bar math below holds, and end on C, its home chord, where this lesson ends on A minor.

• Chords: A minor, F, C and G, two bars each, eight bars in all.
• Kick and snare: kick drum on beats 1 and 3, snare on beats 2 and 4, in every bar.
• Hi-hats: closed hi-hat on every eighth note, eight hits per bar.
• Bass: the root of each chord, the note the chord is named after, played on each kick hit.
• Pad: the four chords held for their full two bars on a soft, sustained synthesizer sound.
• Hook: a melody built only from notes in the chords. In the first bar of each chord it plays the chord’s three notes up and back down, one per beat, so A, C, E, C over A minor, then holds the top note for the whole second bar. Over F that is F, A, C, A and then a held C, over C it is C, E, G, E and a held G, and over G it is G, B, D, B and a held D.

Every note in the hook belongs to the chord under it, so it cannot clash with the pad or the bass. Our guide to learning music theory as an adult explains what a chord’s three notes are and why a line built from them sits comfortably over the harmony. For the same ideas counted on the piano roll grid, see our guide to music theory for making music in a DAW.

Before going further, save a copy of the project under a new name. The loop is now the source material, and the arrangement happens in the copy.

Lay Out All 72 Bars Before Writing Anything New

Repeat the loop until every part plays from bar 1 to bar 72, nine times in all. Play it through once. It is three minutes of the same 20 seconds, and now it is at least the right length.

Then mark the sections. Every DAW has markers or locators, flags pinned to a bar on the timeline, and six of them go in at bars 1, 9, 25, 41, 49 and 65, labeled Intro, Verse, Chorus, Breakdown, Chorus 2 and Outro. The section lengths are 8, 16, 16, 8, 16 and 8 bars. In many styles, sections run in multiples of four, eight or 16 bars, according to the song structure lesson in Ableton’s free Learning Music course.

Now arrange by subtraction. Work through the timeline section by section and delete or mute the parts the map below says are silent. Removing is faster than composing, and everything left already works together.

The Arrangement Map, Bar by Bar

The intro runs the pad through a low-pass filter, which lets low frequencies through and cuts the high ones, so the chords start dark and muffled. An automation lane, a line drawn under a track that changes one setting over time, opens the filter across bars 1 to 8, and the hi-hats arrive at bar 5 so the intro has a pulse before the drums do.

The outro carries the one note change in the lesson. The loop’s last two bars are G, and G is not the key’s home chord, so a track that stops there sounds as if another bar is missing. Changing the pad’s chord in bars 71 and 72 to A minor lets the track end where the key began.

Transitions: The Last Bar of Every Section

A section change with nothing in its last bar sounds like a cut in a video. The handover happens inside the final bar of the outgoing section, and there are four moves that cover almost every border in a first track.

1. Remove the kick. Dropping the kick for the last bar, or just its last two beats, makes the next downbeat, beat 1 of the new section, land harder. It costs one click and works at almost any border.

2. Play a fill. In bar 24 the snare plays sixteenth notes, four per beat, across beats 3 and 4. A fill warns the ear that a change is coming.

3. Build and then stop. In the breakdown, the snare comes back in bar 47 on every beat, doubles to eighth notes for the first two beats of bar 48, and plays sixteenths on beat 3. Beat 4 of bar 48 is silent, everything including the pad. One beat of nothing before the final chorus often lands harder than any sound you could put there.

4. Swell into it. Any crash cymbal sample reversed in the DAW rises in volume and stops dead, and placed so its end falls exactly on beat 1 of the new section, it pulls the ear across the line. The intro uses one to reach bar 9.

On beat 1 of each chorus, a crash cymbal marks the arrival. Keep it to the big borders. A crash on every section flattens them all to the same weight.

Contrast Beyond Turning Parts On and Off

Muting a part is the coarse tool. Three finer ones separate sections that contain the same parts, and the map uses all three.

Density. Hi-hats on quarter notes, four per bar, and then on eighth notes give the same kit two energy levels, which is why the verse changes at bar 17 and needs no new part to do it. The bass moving from two notes per bar to eight at bar 33 adds drive to the chorus the same way.

Register. A part moved an octave up sounds brighter without any new notes. The second chorus doubles the hook an octave higher, by copying it to a new track and raising every note 12 semitones, the half steps that make one octave, instead of writing a second melody, because a last chorus that repeats the first one exactly sounds like the loop again.

Space. The breakdown, the quietest point since the intro, gives the final chorus something to rise out of.

A rule of thumb that falls out of the map: nothing runs longer than eight bars without something entering, leaving or changing. It is not a law of music, and plenty of hypnotic dance tracks break it on purpose. For a first finished track it keeps the listener’s attention from drifting, and it gives you a concrete test for any stretch that feels long: count its bars.

How to Finish It

A track is finished when a person who is not you could press play on it. Before that point it is a project. This checklist is the definition used in this lesson, and a track that passes every line is done even if you would change things later.

• Every section has a marker, and the six markers match the map or a map you changed on purpose.
• Every border has a transition in the outgoing section’s last bar.
• Nothing runs longer than eight bars without a change.
• The last chord is the home chord, and the final sound rings out instead of being cut off at the end of the timeline.
• The meter on the master channel stays below 0 dB. The master channel is the final output every part runs through, and 0 dB is the highest level a digital file can hold. Anything pushed past it is flattened, which is heard as crackle and distortion. Turn down the loudest parts rather than only the master volume.
• The export is a WAV file, the uncompressed audio format every DAW writes, named with the track title and the date, and you have listened to the exported file from start to end without stopping, once on headphones and once on a phone speaker.

The last item catches what the DAW hides. A part that sounded balanced inside the project can vanish on a phone speaker, which reproduces little of the bass, and a phone is a likely place for someone to hear the track first.

Set the deadline before starting. One week from the first marker to the exported file is enough for this map, and an exported first track with flaws is worth more than another month on the loop. Our guide to writing a song makes the same case from the songwriter’s side, and our guide to staying motivated in music lessons covers what keeps a weekly habit going once the first track is out.

Bring the Map to a Lesson

A production teacher listens differently when the track has bar numbers. Send the exported file and the arrangement map before the lesson, and the teacher can listen once through without stopping, the way a listener will, and note the exact bar where their attention dropped. Feedback then arrives as “the verse needs its change at bar 17 to be bigger” rather than “the middle drags”, and you can open the project and go straight to it. For a teen working toward a college application, our guide to production lessons for teens sets out what production programs ask applicants to submit.

The lesson itself runs over a shared screen with the DAW’s audio sent directly into the call, as our guide to what to expect in a first online music lesson describes. The most useful homework after an arrangement lesson is a second track built on the same map with a new loop, because the second time you use the map without following the lesson.

How to Find a Music Production Teacher on Tunelark

Every Tunelark teacher is vetted by working musicians and educators for teaching quality before they can list. Each teacher sets their own rate and shows it on their profile, and Tunelark handles scheduling, billing and support.

• Open the teacher list at tunelark.com/find-a-teacher, filter by instrument, and read each bio for the DAW the teacher uses.
• Choose a lesson length of 30, 45 or 60 minutes. An arrangement lesson that plays a three-minute track through twice fits more comfortably in 45 or 60.
• Book a trial lesson. The first lesson with a new teacher is that teacher’s rate minus $25, for whatever length you choose, so trials start at $14.
• Bring an exported file of your loop or your arrangement, with its bar numbers written down.
