Sometimes I'll see on discogs.com a song will say string arrangements by so and so... and it's an original song by them.
- Can original compositions be arrangements?
- What makes an arrangement?
- Can it be like making the song you composed in a certain style of music or genre than your first draft?
Cambridge dictionary defines arrangement as:
a piece of music that has had changes made to it [so] that it can be played in a different way, especially by different instruments
If the piece of music can be played in a different way, isn't that also considered an original piece?
