The diatonic phrygian tetrachord - just rolls off the tongue, doesn't it? Well, maybe you're not familiar with this expression. It's actually a sequence of four musical notes. But I can pretty much guarantee you've heard it played over and over again.

If you're a classical guitarist, it may be impossible to resist the pull of one iconic piece: the Concierto de Aranjuez by Spanish composer Joaquín Rodrigo. Many musicians regard it as the holy grail of guitar repertoire, including a man so big in the classical world he is known by only one name: Milos.
Once upon a time, Jenny Lewis was one of those child actors you might have seen on shows like Growing Pains and Mr. Belvedere. But then she started making music, and in the late '90s that started taking off. Once her band Rilo Kiley started scoring hits, it was hard to go back to sitcoms.
Marisa Anderson knows where American guitar music has been and where it is now, and probably possesses an inkling of where it can go. She's studied the history and musical nuance of blues, country and folk music through and through, and ingests it all in a style that's as raw as it true. But mostly, Anderson just wants to kick up some dirt — which isn't easy here, given that the NPR Music offices are relatively clean. (Mind the towering stacks of CDs, though. They could topple over at any time.)
Marisa Ronstadt bears a musical name but she has her own style, which seems to be a mix of Mariachi, Classic Rock, Soul, R&B, Indie Pop - maybe she'll fill in any that we've missed. She's played music since she was seven and has her own band now "Marisa Ronstadt And The Know-It-All's." Their debut album is "Blueberry Moon." It's out now - let's hear a little.
