Saturn, how is song writting different form song composing?

Saturn, I am a banana. 编曲 as two separate words I know. As a combine word I have no idea. It is not listed in my dictionary. Please give more explaination.

It may be the correct word, Saturn. Tell me what is the task involve in song arrangement?

structure means, for example:

intro - v1 - v2 - chorus - interlude - v2 - chorus - bridge - chorus - outro

then the intro and outro are created as arrangement, so as the interlude and how all instruments are played. composing or song writting is just the melody and lyrics and maybe chords (but arranger can change the chord).

to make it even more simple to understand, "remix" is also a kind of arrangement.

usually, 80%~100% are done by specialist "arranger", at least in the chinese market. there're also co-arranger like main arranger arranged everything and a special arrange just the strings part.

in western country, or even japan, they're done by the composer himself. producers also will do quite a lot as he/she'll involve lots of recording sessions and they'll put in lots of ideas there. heck, some producers are also the composer and also the arranger, which is quite common in japan.

then, sessionist and even mixing engineers can also input some ideas too, like guitarist replacing the midi guitar mockup, he can input some ideas too. sound engineers can copy some of the parts and paste it else where (maybe some special effects too).

how you give credits, it's entirely up to the whole team. but it's usually the one who did 80%~100%, or 50%/50% you'll see 2 names, or specifically like "arranged by xxx, strings by xxx".

local arranger usually don't deal with backing vocals, producers will hire backing vocal specialist, at least commonly done in the chinese market. but it's not uncommon for singers to DIY, or producers taking over the job.

and yes, arranger must know how all instruments are played, and more importantly, how to let them shine - you don't use classical guitar to play power chords, or piano to play like bass, etc etc. nowadays arranger all use MIDI to do arrangement, and most of the time, all of the tracks are MIDI because sampling technology nowadays are so good and computers are powerful enough to handle detailed and huge amount of samples. but it's up to the arranger (MIDI programmer) to make the midi track sound like real thing. still, nothing beats the real deal, but you know, it's about budget.

back then, almost everything are recorded with live players, and obviously sound so much more lively...
