5 songs. Create one like this.
MuziAI has 5 AI-sung sample songs in the acoustic category, and the short version is: slow, harmonically sparse, and parked in E-flat major or D major. Four run at 72 BPM, all five use one of those two keys, and the median is about one chord per bar. This describes MuziAI's five samples, not acoustic music as a genre.
Measured profile
Figures are read from the score the system writes for each song. The right-hand column is Country, the other genre whose tag asks for acoustic guitar.
| Metric | Acoustic (5 songs) | Country (2 songs) |
|---|---|---|
| BPM (min / median / max) | 72 / 72 / 100 | 100 / 100 / 100 |
| Key | E-flat major 3, D major 2 | C major 1, E-flat major 1 |
| Length | 178 to 210 s, median 202 | 150 to 192 s |
| Bars (median) | 63 | 72 |
| Chords per bar | 1.06 | 1.48 |
| Vocal range | 17 semitones | 16 semitones |
| Voice | male 4, female 1 | male 2 |
| Language | Vietnamese 2, Portuguese 2, English 1 | Vietnamese 1, English 1 |
MuziAI's country samples sit at 100 BPM and change chords more often (one reaches 1.97 per bar), while the acoustic ones are slow and linger. The acoustic median of 1.06 includes "Sleep, Little Star", whose score has no chord symbols at all; the other four range from 1.0 to 1.54.
How MuziAI builds this genre
Choosing Acoustic opens the style description sent to the singing model with "Acoustic, acoustic guitar, warm, intimate, simple arrangement". The rest comes from each song's settings:
- Mood: peaceful 2, nostalgic 2, romantic 1.
- Instruments: all five add acoustic guitar; only "Gửi Bố" adds strings. None asks for drums or piano.
- Techniques: backing vocals 2, breathy intimate vocals 2; harmonies, vibrato, an a cappella intro and a fade-out once each.
Inside the samples
"Hương Thu Phố Cổ" and "Gửi Bố" open on the same loop, Eb, Bb/D, Cm7, Ab, with the bass stepping down E-flat, D, C. "Hương Thu Phố Cổ" is the only one at 100 BPM, with 16-bar verses and no pre-chorus: 75 bars, yet only 178 seconds. "Gửi Bố" runs at 72 BPM with an 8-bar verse plus a 5-bar pre-chorus: fewer bars (63) but longer (208 seconds), and the busiest harmony of the group (1.54 per bar).
"Chuva no Rio" and "Saudade do Meu Mar" share D major, Portuguese lyrics and a male voice. The first just rocks between Dmaj7 and G, yet its vocal line holds 414 notes, the most of the five. The second goes D, F#m7, G, then Gm, a chord borrowed from D minor that gives a bittersweet turn suited to its nostalgic mood. "Sleep, Little Star" is the most compact: 168 notes across 14 semitones.
Getting better results
- Pick the tempo on purpose. "Slow" gives 72 BPM like four samples; "Medium" gives 100, noticeably brisker for a calm song.
- Plan length up front. At 72 BPM every 10 bars adds about 33 seconds, so write fewer stanzas for a shorter song. The lyric writer can lay them out.
- Want a lift before the chorus? Give it its own short stanza. Three samples have a 4 to 6 bar pre-chorus; the other two go straight to the chorus.
- Borrow a chord loop. In the existing-score panel of the song generator, pick a sample and keep "melody + chords" or "melody only".
- For a soft female voice, copy "Sleep, Little Star": female voice plus breathy intimate vocals.
Limits
Five songs, each generated once, cannot show that acoustic "always" lands in E-flat or D. Tempo reflects the speed setting more than the genre. The numbers come from the score, not the audio, so they say nothing about how natural the guitar sounds. Listen for yourself in the sample library.
