I'm really enjoying a disc I took a flyer on, the string quartets of
Joseph Marx (the Lyric Quartet's world premiere recording on ASV). The
Quartetto Chromatico is okay, but for me the real pleasures on this disc
are the Quartetto in Modo Classico and the Quartetto in Modo Antico.
But I need some help on the liner notes.
Discussing the Antico, Brendan Carroll says that the first movement
is based on the Mixolydian mode, and the slow movement derives from the
Phrygian mode. I've heard these terms before but way off in pre-history.
What exactly is a mode? And how does a Mixolydian differ from a Phrygian?
