Piano, Pads and Vinyl in Every Spec Sheet

Ten spec sheets, ten different songs, and a few phrases that never change: a piano, pads, vinyl and a mix tag. Here is what stays fixed and what moves.

Every song of dear(you); vol.1 has a design document, and every design document ends with a "Suno Style" block: the genre, the instruments, the mood and the mix that were requested when the song was commissioned. Most posts here read the lyrics. This one reads the block, and asks a plain question: across ten sheets, what is the same?

First, the scope. We read only the Style block of each of the ten design documents. They were written on 2026-07-04, and they are requests we typed, not a description of the audio we have heard. A tag such as "Vinyl Crackle" asks for a sound; it does not tell us that the sound is audible in the finished track, and we did not check. The music is made with AI (Suno); the lyrics are drafted by AI and reviewed by a person.

What is on all ten sheets

PadsInstruments, every song10 of 10
VinylInstruments in 01 and 03 to 10; "Vinyl Texture" under Mix in 0210 of 10

The piano is the one element that never leaves, though its name changes. Songs 01 to 04 ask for a "Soft Piano" (03 adds a "Warm Electric Piano"), songs 05 and 06 for a "Soft Felt Piano", and songs 07 to 10 for a "Felt Piano". So the name is trimmed in two steps, from "Soft Piano" to "Soft Felt Piano" to "Felt Piano", and it changes at songs 05 and 07 only. Whether anyone would hear that difference is a question for the audio, not for this table.

The pads are listed in all ten under six wordings: Gentle Pads in 01, 07 and 08, Gentle Pad in 02, Ambient Pads in 03 and 06, Soft Pads in 04 and 09, Gentle Ambient Pads in 05, and Warm Pads in 10. The vinyl is the one that moves between fields. In nine sheets it is an instrument, "Vinyl Noise" or "Vinyl Crackle". In song 02 it is written as a mix instruction, "Vinyl Texture", and the instrument list there names a "Light Lo-fi Beat" and "Coffee Shop Ambience" instead.

The mix tags, with two swaps

Two phrases come back in the Mix line. "Warm Analog Tone" is on the sheets of 01 and 03 to 10, nine in all, and song 02 has "Warm Reverb" in its place. "Wide Stereo" is on 02 to 10, also nine, and song 01 has "Wide Reverb" instead. Songs 03 to 10, eight of them, carry both phrases together. So the two outliers each differ from the rest by one word, and they are different songs. The genre line follows nearly the same pattern: "Ambient Lo-fi" is the genre of nine songs, and song 10 reads "Ambient Piano · Sleep Lo-fi".

The vocal line

One more thing is shared: the way each sheet describes the singers. In all ten, the English version (Version A) is a sweet female voice and the Korean version (Version B) is a gentle, whispering male voice, and each version gets a whisper in the other language. English by a Woman, Korean by a Man and Whispers in the Other Language read that rule. The sheets differ from the third song on in one detail: an opposite-gender harmony is requested from song 03 on (in the chorus in 03 and 04, in a section the sheet does not name in 05, and in the Final Chorus in 06 to 10), and the sheets of 01 and 02 do not mention one.

What moves

The things that do not stay fixed are as informative as the ones that do. Guitar is on the sheets of 01 to 09 and absent from 10, which Closing the Album with Its Slowest Song reads. Strings appear only in 04 and from 06 on, and rain-type textures show up in eight of the ten under different names, from "Light Rain Ambience" to "Rain Fade Out". The tempo changes from 64 to 74 BPM as The Tempo Ladder of Ten Songs lays out. Read together, the sheets look like a template with a few controlled dials, not like ten unrelated briefs.

What we are not claiming

  • That any listener can hear a piano, pads or vinyl in each song. We read requests, not audio.
  • That the sheets were copied from one template on purpose. The documents do not say how the blocks were written, and we draw no stronger conclusion than the overlap itself.
  • That the renamed piano or the swapped mix words made an audible difference.
  • Anything about how a listener will feel. No medical or other effect is claimed.
