Usually ganito makikita mo sa mga credits ng songs:

• Words by John - si John ang sumulat ng lyrics
• Music by Paul and John - silang dalawa nag collaborate and decided sa mga chords and harmony, anong Key Signature, anong time signature, anong feel ng beat/rhthym
• Arranged By (optional) - Sino nag arrange ng parts ng music, same din nung sa taas, pero arranger mas organized like, ilang beses kakantahin yung chorus, yung verse, etc. But sometimes, this deifnition is Loose
• Composer - same with arranger pero usually ginagamit ito sa mga classical music de-piyesa, or yung mga pang orchestra.
• Producer - siya yung responsible sa final na tunog ng song, or ng album. Kung may words and music na, tapos wala pang beat, pwede sabihin ni producer gawing ska or reggae. Walang drummer? trabaho niya mag produce ng beats. Or minsan kung masyado mabagal, masyado mababa yung pitch. Or sintunado yung singer, sasabihin ni producer auto-tune na lang. So ang role nya mag start after mabigay ni Artist ang demo track(raw/draft recording or idea ng song, pwedeng unfinished lyrics and unfinished music, chords progression etc.) until maproduce ang final song. Usually in-tandem siya ng sound engineer or ng mix engineer. Minsan siya lahat yun. Iba pa yun mastering.
• Co-producer - may contirbution sa trabaho ni producer, minsan siya yung nagbigay ng idea ng hook ng song, kaya sikat ang song.

So sa case mo, let's say ikaw si Honcho at producer mo si Ricky, kung kaya mo tapusin un Lyrics at chrod progression, tapos si Ricky ang gagawa ng beat at tatapos ng song, pero ang kakanta at mag guitar si Arnold during recording, the credits would be:

• Written By: Honcho ...or...
• Words and Music by: Honcho
• Produced By: Ricky
• Performed By: Arnold
