R& B: Rhythm and blues Rhythm and Blues
percussion is mainly used as accompaniment, and jazz is also often used. Of course R& B mainly black music, Japanese R& B is much softer, and the piano is also used as accompaniment.
There are many variations in singing, and there are no specific rules. Castle Peak テルマ & SoulJa's ここにぃるよ should be regarded as a typical Japanese R&; B, there are also the use of harmony, but the average black r&; B mainly solo more.
funk: funky black jazz
The accompaniment is mainly percussion, but also bass and guitar. The rhythm is obvious, the speed is fast, and the singing is exaggerated.
funk is mainly used as dance music, but harmony is often used.
If you take SH's songs as an example, I don't know if "The World with Sound" is counted (Laughter, REVO likes to mix various styles together ...)
Blues: Blues (this is transliteration)
Blues are closely related to American country music. Blues has the meaning of sadness in English, so the tune is more soothing, and the lyrics and singing are also more gentle and sad.
The accompaniment is mainly guitar, but also harmonica and piano. Blues' scales seem to have profound knowledge, and I can't explain them if I don't know professional music.
SH seems to seldom use acoustic guitar, so the logo of Blues is hard to find ...
JPOP: Japan-pop, Japanese pop music.
Jpop has a wide range, and its style is lyrical or light, and it has been mixed with japanese pop's factors on the basis of pop music. Because it is popular music, there are many accompaniment instruments, such as percussion, guitar, piano and electronic music.
in the second issue of p>SH, the styles of singers KAORI and YUUKI are relatively JPOP, and the whole ROMAN is also very JPOP.
personally, I think that the "pseudo-SH" composed by Wei Pu +REVO, "Sand and Dust", is the most JPOP in SH history.
Anime: animation music
is mainly the theme song, OP\ED\IN, impression song, role song and so on tailored for animation.
The artistic conception of lyrics and melody is relatively suitable for related animation, and the accompaniment instruments are also very diverse.
In fact, Sound Horizon is not particularly involved in the scope of Anime, and all it can find is probably a set of Gunslinger Girl Image Album "Poca Felicita"
Comparatively speaking, some fan albums in the early SH period can barely be regarded as Anime.
speaking of chanting, r&; There will be many in B, and some JPOP will also have them (for example, Serenade and gloria in カノン, and Gloria is also a song in Anime). Mainly as a style of arrangement. Other Anime music will also have lines or lines (there are more role songs).
The last two additional questions are really incompetent ...
Sorry.
