In Suno Veritas

Posted by me on 8.5.2025 in Recordings | Comments Off on In Suno
Veritas

And now for something completely different.

Meanwhile Suno 4.5 happened, and I'm totally blown away by it!

Computer-generated music has fascinated me since my youth. I even
wrote my master thesis at ETH Zurich on AI and music. But Suno is in
a completely different league to all previous attempts (and there
have been many). So it's high time I played around with it. This
technology definitely has a high addiction potential!

In this post, I explore Suno's ability to create covers of existing
songs - my songs, of course. As before, the songs are available under
Creative Commons by-nc-sa. Since algorithmically generated works are
not copyrightable in almost all countries, I am taking the liberty of
making the covers generated by Suno available here as well.

This post even made it onto the front page of Hacker News!

Generating from direct live recording

Let's start with the original track which I composed and recorded in
last November (all instruments are played live by me simultaneously,
without overdups): 2024-11-25/1 (from this album).

And here the first cover generated by Suno; as style I entered "prog
jazz rock"; the result is pretty close to the original - just
incredible how this algorithm works - like magic: 2024-11-25/1 Jazz
Rock

For the second attempt I was more currageous and added a brass
section with a sax solo, still in jazz rock style: 2024-11-25/1 Jazz
Rock Brass Section. The result is just great and very groovy, even
with a jazz guitar solo in the middle, and I like how the theme kicks
in at the end.

And since my wive is very fond of the various house tracks she found
on Suno, here a version in a combined jazz rock house style, still
with brass, and some electronics in the middle: 2024-11-25/1 Jazz
Rock House Funk. No one can keep still with this groove.
Unfortunately the track just ends abruptly.

And last but not least, a rap version with lyrics about computers and
music, put together for me by Perplexity; it has different parts and
breaks and a great sax solo at the end: 2024-11-25/1 Jazz Rock House
Funk Rap. Now if that isn't a hit!

Generating from direct sequencer mixdown

Here are some tracks from my ToyLand album, which I regenerated with
Suno:

Let's start with an improvised R&B multi-track piece; here is the
original track from 2005. And here is what Suno made of it.

Now for RTS, an old jazz-rock piece from the eighties; here is the
original track fed into Suno. And here what Suno made of it. It's
interesting to note that Suno had problems recognizing the chords of
the bridge.

Now a bossa nova jazz rock piece I wrote for my band in the eighties
called "Radha Kundha"; here is the original track fed into Suno. Here
are two generated versions:

  * Latin Jazz with small band with acc. guitar; theme and chords are
    pretty accurate.
  * Cuban orchestra with acc. guitar; here Sudo composed a prelude
    before the orchestra kicks in.

"Turn around" is yet another piece from the eighties which I composed
for my band at the time; here is the original track fed into Suno.
And here whate comes out:

  * Cuban version; theme is perfect, some chords don't fit, and Suno
    added another part, which is ok.
  * Bossa nova version; here the chords fit and the piece closely
    follows the original, but it missed a note in the theme; still
    great.

"Lonely Friend" is a piece I wrote in the early nineties, which I
wasn't able to record until ten years later; here is the original
track fed into Suno. And here the result:

  * Acc. guitar and piano; both theme and chords are not very
    accurate, but still beautiful.
  * Electric guitar, soprano sax and piano; again neither chords nor
    theme fully accurate, but beautiful.

Here are some tracks from this album from 1993:

Here is the original recording. And here two examples of Suno
interpretations:

  * Close to original african jazz rock
  * Bulgarian brass band jazz rock

Here another original recording. And here again two examples of Suno
interpretations.

  * Jazz rock band with true live feeling (Suno came up with this
    itself)
  * Disco funk dance production as from the eighties

And here another original jazz rock recording (as I did a lot in the
nineties), and what Suno created from it.

Generating from live performance recording

Here are some tracks from a (not particularly good) live recording
from this 1989 album.

"Turkis" is a 7/8 piece which is part of a larger composition of mine
from around 1985; here is how we played it in 1989. And here is a
version generated with the Bulgarien brass band by Suno; pretty
accurate and I very much like the drums.

Here is a slow ballade which I wrote at the time of this concert: A
Septembers War. And here is the interpretation by Suno; the piece
apparently was a challenge for the algorithm; but still beautiful.

Generating from studio multitrack mix

The following pieces are from this album from 1987, which I recorded
on a Fostex eight track tape machine and mixed it down to DAT.

A jazz rock composition of mine, and the Suno interpretation, which
is only a subset of the piece because of the two minute limitation.

Yet another jazz rock composition of mine, and the Suno
interpretation; the harmonies were apparently a challenge for Suno.

Here is the original recording of a ballad called "High" which I
wrote at the time. The interpretation by Suno is surprisingly
accurate and comes very close to the original.

More to come.
