****At :09 and 2:06 Was there anything amiss there?****
Nothing that is not intentional and musical, if you're hearing what I hear. At .09 (actually, at .10) he just cuts the melody short; varies it, if you will, like many players do. Its all the more obvious with a familiar melody like NIT. Notice how he does the same thing again at .17. It's just his personal interpretation of the melody. It actually makes it interesting and it did what he intended: caught your attention. At 2:06 it sounds like he turns away from the mic a little and when he plays the multiphonic the note doesn't speak right away so his sound seems distant and almost like a mistake or missed note; it's not. Good for you for listening for those nuances. BTW, a multiphonic is when the player sounds more than one note at a time. It's a great sound; very expressive.
Classic (and some of the first ) use of multiphonics:
