Day 5: Choosing Loops by Category and Genre

Day 5: Choosing Loops by Category and Genre

Friday, August 7th, 2026

Objectives

  • I can name the job each category of loop does in a set.
  • I can explain why four loops from the same category do not make a song.
  • I can explain how choosing a genre first makes the rest of my choices more cohesive.
  • I can build a set by choosing a genre and then filling each job from it.

Warmup: Which One Is More Cohesive?

Open Soundtrap

Find 5 Guitar loops and put them all together in one project at the same time.

Listen to it.

How does it sound? Good? Bad? Why?

Checkpoint: Warmup

  • I made a Soundtrap project with 5 Guitar loops.
  • I can describe how it sounds.

Work Session: Loop Types

Every category of loop has a job. A piece of music works when each musical role is filled clearly:

CategoryJob it doesWhat happens if it is missing
Drums / PercussionSets the beat and the energy.No pulse
BassAnchors the harmony at the bottom.The music sounds thin and hollow.
HarmonyFills in the chords in the middle.There is nothing filling the space between the bass and the melody.
Melody / Main LeadThis is the main part people sing along to.The music doesn’t have a clear focus.

What happens if you fill a role many times?

This is why four drum loops do not make a song. Four drum loops is one job done four times, and three jobs left undone. The same is true of four bass loops or four synth leads.

Is this a rule?

No, not every great piece of music has one clear drum, one clear bass, one clear harmony, and one clear melody. This is the simplest recipe though for making a good song using loops.

Key Vocabulary

Cohesive
Holding together as one piece, so the parts sound like they were meant for each other.
Genre
A category of music that shares a sound — hip hop, rock, EDM, cinematic, lo-fi.
Arrangement
Which parts play, when they play, and how they fit together.

Checkpoint: Work Session

  • I can name four musical roles a loop can fill
  • I can explain why having four loops from the same category does not work.
  • I can explain why missing a musical role makes a song sound incomplete.

Genre

Filling every job is not enough on its own. A cinematic string loop, a lo-fi drum loop, a metal bass, and a salsa piano fill all four jobs — and still sound like four different songs playing at once.

Loops in the same genre were built with the same assumptions: similar tempo, similar instruments, similar production, similar feel. Choosing a genre before you start browsing narrows thousands of loops down to a few dozen that already agree with each other. You are not limiting yourself — you are letting the earlier decision do the work of the later ones.

That is the order that works:

Open the Genres menu and commit to one before you preview anything. This is the decision that makes every choice after it easier.

Build One

Make a new project and build a four-loop set this way, start to finish. Pick a genre you did not use in Set 2 of your scavenger hunt.

Name it after your genre so you can find it later.

Checkpoint: Work Session

  • I picked a genre before I previewed any loops.
  • I set my key and tempo before adding loops.
  • My set has one loop for each of the four jobs, all from that genre.
  • I balanced the tracks and saved the project.

Closing: Cohesion Check

Play your new set for a neighbor and answer:

  1. What genre did you choose, and which loop makes that genre obvious?
  2. Is this set more cohesive than the one you shared yesterday? What made the difference — the genre, the four jobs, or the balance?

Save your project and log off.

Standards

  • MSMTC8.CR.2 — Select and develop musical ideas for defined purposes and contexts (building a set by choosing a genre first and then filling each job once from inside it).
  • MSMTC8.RE.1 — Choose music appropriate for a specific purpose or situation (citing the category a loop belongs to and the genre it comes from as the reasons for choosing it).
