for example could u play a neighbour tone twice or got from a chord tone to an nct then to another nct. I was looking at jackson 5's want you back and this appeared to be the case
this is written in A flat major
during the middle of the measure it goes from an Aflat to two B notes then to then to several f notes then to Eflats. i figured that these are passing and neighbour tones is their a name or way to analyse nct's being used consecutively.
