Modes are seven-note scales that each have their own colour: Dorian is a minor scale with a brighter sixth (hopeful, jazzy), Lydian is a major scale with a raised fourth (dreamy, floating), and Phrygian is a minor scale with a lowered second (dark, eerie). They're great words for describing a mood. When we measured our own AI-made tracks, Suno usually got the requested home note right when we asked for a plain key like "E minor", but was much less reliable with the more exotic modes.
The modes, in lofi terms
Play all the white keys from a different starting note and you get a different mode:
| Mode | White keys from | Colour | In lofi |
|---|---|---|---|
| Ionian (major) | C | bright, settled | morning, coffee |
| Dorian | D | minor but hopeful | jazz, late afternoon |
| Phrygian | E | dark, exotic, uneasy | night, spooky lofi |
| Lydian | F | dreamy, weightless | space, sleep, daydreams |
| Mixolydian | G | relaxed, bluesy major | warm grooves |
| Aeolian (minor) | A | sad, reflective | rain, memory |
Dorian is lofi's favourite mode. It's the sound of a minor chord that doesn't feel sad, the backbone of a lot of jazz and neo-soul.
Lydian is the "floating" sound in film music when something magical happens. Slow it down and add pads and you get dreamy, weightless lofi.
Phrygian is the darkest of the common modes, thanks to that lowered second note right above the home note.
Our test: did Suno follow?
Many of our albums were named after the key or mode in their prompt: "Dusky Mirage in F# Dorian", "Lydian Echoes", "Abyssal Echoes: E Minor Odyssey". We ran a key-detection tool over the tracks hosted on this site and compared its answer with what the prompt asked for. The tool finds the home note and whether the track feels major or minor; it can't tell Dorian from plain minor, so we only checked the home note.
Albums where Suno clearly followed:
| Album | Asked for | Tracks measured | Home note found |
|---|---|---|---|
| Whispering Cosmos | F blues | 12 | F on 10 of 12 |
| Abyssal Echoes | E minor | 11 | E on 9 of 11 |
| Midnight Raga Whispers | F# major | 6 | F# on 5 of 6 |
| Ebbflow Blues Serenity | Eb blues | 7 | Eb on 6 of 7 |
Across the 22 albums whose prompts named a key and that have tracks on the site, the measured home note matched in 12. The misses cluster around the unusual requests: both Lydian albums, "Ab Mixolydian", "Ab Dorian" and "Gb blues" all came back centred on a different note.
Two caveats: many albums have only one or two tracks on the site, and automatic key detection is itself imperfect, especially on ambient tracks without a clear bass line. Treat this as a rough guide, not a verdict.
What this means for prompting
- Plain keys work better than exotic modes. "E minor" is more likely to come out in E minor than "B Lydian" is to come out Lydian.
- Describe the feeling of a mode as well as its name. "Dreamy, floating major with a raised fourth" or "dark minor with an exotic, uneasy second note" gives the model something to go on.
- Don't count on flats and sharps. Keys like Ab, Db and Gb missed more often in our set.
- Check by ear. If the mood is right, the exact mode matters less than you think.
Our real prompts, with how each album did, are in Suno lofi prompts. For the chords that give lofi its colour, see lofi chord progressions.
