Hmmm...never been asked before to comment/dissect something I've played. I listened back to hear what was happening at those points mentioned. Must say that this is not a written piece and certainly not practiced. It's an improvisation based on what the guitarist was playing. It's modal, which makes it easier as there are no changes. I just need to "hear" a line and play what I'm hearing in my head.
Still not sure if jrintaha meant wrong notes or out of tune?
To answer Chris: I'm lazy and don't ever try to identify the mode or give it a name as this doesn't do anything (for me) in terms of hearing a melodic line. It may help some to know the notes involved so that they can play something that fits within that mode. For me playing is about melody which isn't the same as tossing out technical variations. It's about trying to give the listener a [FONT=&]non-intellectual[/FONT] experience, a story that they picture in their head, a place, feeling, etc. As some have commented much of what we play sounds like a sound track to visuals.
I don't always connect what's in my head with what comes out of the horn (pesky fingers!). When that happens I do what most players would do: bluff and cover. That didn't happen at the times that were identified (1'46, 1'48 and 1'51), so I must have meant to play those notes. If they are the ones I think they are they are tension passing tones, especially the one starting the phrase.
We each have listening/hearing filters that reflect what we are familiar with. Many would listen to Asian or African ethnic music and (unless they already had a connection and understood the "vocabulary") just hear it as noise that sounded all the same.
At the risk of sounding like Mike (he does this much better): The player isn't responsible for how the listener hears/listens. We just try to play with integrity and be true to our own musical thoughts. Listening is always subjective.
Being able to give a particular mode/scale/chord a name doesn't make it more understood or listenable, it just pidgin-holes it. Musicians need to communicate between each other so that they can play together; that's where the nomenclature is most useful. I'm basically lazy so just use my ears.
