I recall an experience in an old band I was in. The guitarist wrote a song and I added in my bassline for the intro which was 8ths on the root note. At the time he asked can you do this/that etc, so I tried but decided to stick to my guns on what I’d originally come up with.
Said guitarist then decided to record the song (without the band, just him, for our website - this was him all over, sadly).
Grudgingly (very grudgingly) he admitted to me that after trying many things out on the bass he realised that my 8ths on the root intro were what was right for the song.
It was a rock song with a killer guitar riff for the intro, what he’d originally wanted was something like Flea bouncing up & down all over the place, whereas as he found all that did was get in the way of his killer guitar riff.
