Composer & Arranger, Did Ayu choose it herself?

[AngelSenshi]

Let's see if I can try to explain this easily.

With the writing process of a singer, in Ayu's case most of all, first she's sent the melody (composition made by a composer) and this is usually the vocal melody stripped down the barest sounds. Have you ever heard an orgel? Sometimes they sound like this sometimes the melody is sung with 'lala lala' by the composer or by an apprentice who works closely with the composer. Then the writer of the lyrics (Ayu in this case) will either write lyrics to fit the melody immediately (this seems most likely in Ayu's case) or write sentences and then fit them to the melody later. After this, the person in charge (again, this is Ayu) decides on the sort of arrangement she wants. The arrangement is what makes up the song; the pianos, the violin, the guitar, the bass, the drums, just all the instruments and in what way they will play and what they will sound like. An arranger usually has a distinct sort of sound so if you want a song to sound a particular way (in Ayu's case; the way she sees the song being with her lyrics) they decide on who the arranger will be. From then on, the arranger and the artist collaborate to come to a result that is closest to the artists vision.

When she worked as CREA, i.e she did the melody composition herself, she most likely did the lyrics and melody at the same time as this is how it is usually done when a vocalists put lyrics to their own melody. Or else, she fitted her own melody with her lyrics after; I think the latter is what happened with M, but the former is what happened with the other songs that she composed.
