AI Music Rock
Rock needs electric guitar, strong drums, and a chorus you can shout. Want it heavier? Check out Metal.

Rock on MuziAI has 3 AI-sung sample songs, and all three are fast (128-129 BPM), long (249-292 s) and built on the same tonic note. The takeaway: rock has more bars than any other genre on the site but the sparsest sung melody, because instrumental sections fill a large share of each song. This describes MuziAI's samples, not the rules of rock.
Measured profile
| Metric | Value |
|---|---|
| Sample songs | 3 |
| Tempo (BPM) | 128, 128, 129 |
| Key | D-sharp minor (2), E-flat major (1) |
| Length | 249-292 s (median 257) |
| Bars | 133-157 (median 138) |
| Chords per bar | 1.02 (0.99-1.11) |
| Melodic range | 17-22 semitones |
| Melody notes per bar | 1.79-2.38 |
| Voice, language | 2 female, 1 male; 2 Vietnamese, 1 English |
The figures come from the sheet music (ABC notation) the singing model writes with each song. A median of 138 bars is the highest of 19 genres, and «Mười Bảy Nổi Loạn» alone has 157, the most among all 58 samples. Yet two rock songs have the fewest melody notes per bar on the site (1.79 and 1.96). D-sharp and E-flat are the same piano key, so all three share a tonic and differ only in major or minor color. The 128-129 BPM is simply MuziAI's Fast setting.
How MuziAI builds this genre
The style description opens with Rock, electric guitar, powerful drums, energetic. «Đứng Dậy Từ Tro Tàn» (Rising From the Ashes) adds the Powerful mood, raspy vocals, a guitar solo and a male voice; «Phoenix Rising» adds Powerful, belting, a guitar solo and a female voice; «Mười Bảy Nổi Loạn» (Seventeen and Rebellious) adds Energetic, belting, a drum break and a female voice.
The site's only metal sample, «Chiến Binh Bão Lửa», is also D-sharp minor at 128 BPM with 133 bars. On paper, rock and metal here almost coincide; what separates them is metal's tag cluster (distorted guitars, double bass drums).
Inside the samples
«Đứng Dậy Từ Tro Tàn» and «Phoenix Rising» share one loop, D#m B C# (i, VI, VII), and the same 128 BPM. The Vietnamese male track skips the pre-chorus, runs a 17-bar verse straight into a 17-bar chorus and stretches the bridge to 18 bars; its melody spans 22 semitones. The English female track puts an 8-bar pre-chorus before the first two choruses, keeps the bridge to 8 bars and lets the outro run 18; its melody spans 17.
«Mười Bảy Nổi Loạn» is the only major-key track: Eb Cm three times, then Bbsus4 back to Eb. It has 12 sections, including three verses and two interludes, and its intro, interlude and outro sections cover 61 of 157 bars (about 39%), against roughly 24% and 23% in the other two.
Getting better results
- Expect a long song: at the Fast setting the samples run four to five minutes. For shorter, write fewer sections.
- Choose the harmony through a sample: for a dark minor color, use the button that sings new lyrics over the sheet music on «Đứng Dậy Từ Tro Tàn» or «Phoenix Rising»; for something brighter, use «Mười Bảy Nổi Loạn».
- Match the voice as the samples do: belting for a female voice, raspy for a male one. Treat it as a hint: a separate MuziAI measurement found a «raspy, gritty» male voice tag made the voice no rougher than the default.
- Need room for guitar? Pick the guitar solo option; two of three samples use it, and the model treats it as a suggestion.
Limits
Only 3 samples, all at the Fast setting, so we do not know how rock sounds at 72 or 100 BPM. Sheet music cannot measure guitar distortion, drum weight or vocal grit. Hear all three in the song library, then make your own.
