AI music by genre

By mood

Pick a genre by what the song has to do

Genre is easiest to choose once you know where the song will be heard. A birthday song for your mom needs clear words and a melody people can sing along to, so pop or acoustic beats metal. Background music for a study session should stay out of the way, which is what lo-fi is for. A video opener needs its peak early, so cinematic or EDM works better than a ballad, which takes time to build.

The lyrics you already have narrow things down too. Long, wordy lines suit rap or storytelling country. Short, repetitive lines suit EDM and children's songs. Long lines with open vowels the singer can hold suit ballad and bolero.

Where genres actually differ

Rhythm is what you notice first. EDM and disco put the kick drum on all four beats (four-on-the-floor), bolero rides a slow rumba groove, rap leans on drums and 808 bass to leave room for words, and jazz swings: two eighth notes in a row are not split evenly, the first one is longer.

Instruments come second: distorted guitar in rock, piano and strings in ballads, synths in EDM, dan tranh zither and bamboo flute in Vietnamese folk. Harmony is harder to hear. Pop and country tend to circle three or four main chords of the key; jazz, city pop and lo-fi use lots of seventh and ninth chords, which sound softer and more urban; rock and metal lean on power chords, just the root and the fifth; Vietnamese folk is mostly built on the five-note pentatonic scale. The fourth difference is the vocal: R&B runs and bends notes, rock growls and shouts the chorus, acoustic and indie sing close to the mic, almost speaking.

Quick reference for all 19 genres

The tempo column is the preset to try first in the tempo field: slow (72 BPM), medium (100 BPM), fast (128 BPM). It is a starting point; change it after you listen.

Genres that sit close together

Ballad, bolero and acoustic form the slow, lyrical group: all three put the voice up front and need lyrics with room to hold notes. The difference is color. A ballad sounds clean and wide with piano and strings; bolero brings the rumba groove and the long held notes of Vietnamese golden-era music; acoustic is bare and close, like someone singing next to you. In the library, all 13 ballad samples sit at 72 BPM, the slow preset.

Rock, metal, EDM and rap are the hard-hitting group, and their energy comes from the drums. Rock and metal rely on distorted guitar, EDM on synths and a build that pushes into the drop, rap on words and rhymes riding the beat. Lo-fi, city pop, jazz, R&B and funk/disco are the light, groovy group that shares the same stock of seventh and ninth chords; lo-fi is the slowest and haziest, funk/disco the one you dance to. Folk, Lunar New Year and children's songs are chosen for the audience and the occasion more than for the sound.

When you are torn between two genres

Pick the genre you want to hear in the chorus, then bring in the other one through instruments in the description field rather than by name. Want something half ballad, half R&B? Choose ballad and add smooth R&B vocal, warm keys. Pairing genres that pull in opposite directions, like metal and lo-fi, makes the result much harder to predict.

Try it with one of these ideas

Type one of these into the idea box and create a song, or first listen to a few samples in the same genre in the sample library:

  • “The old ferry at the end of the year”, bolero, warm low male voice, slow preset.
  • “The last night bus”, city pop, medium preset, with 80s synth in the description.
  • “Counting from one to ten”, children's, fast preset.
