What is the proper term for an 'aside' in music (mostly in vocals, but sometimes the score)? Many times these 'asides' MAY not be actually noted in the lyrics.
In Taylor Swifts 'Shake It Off' (2014) @ 0:18 there is a little 'giggle' that is presumably a comment on the 'absurdity of the previous lyric' OR an acknowledgement that maybe the lyric is close to the truth.
In the Rogue Traders 'Watching You' (2005) @ ~1:33-35 You can hear a little laugh (Best with headphones or in an environment with low ambient noise, it is subtle.)
I personally find these little details in the music endearing (when not over done) and notice the absence in different cuts.
I am mostly asking just about the technique in the vocals, not in the score. However if the term is different or technique is considered different a discussion would be interesting.
Just as the 'right' accompaniment can compliment (or sometimes, IMO) surpass any vocals, these embellishments add to the overall character of the tune and add enjoyment. I've wondered for a while what the technique is called.
