Something of a theme for this entry in the Bal Folk Tune Book Project. I noticed that a number of mazurkas I play have a characteristic of beginning the B section with the IV chord. It creates a lovely sense of levitation and, if the song were telling a story, I think that’s when you would know the two of them were really in love!
It happens often enough in mazurkas that I am beginning to think this is a defining trait of a subset, but it doesn’t only happen in mazurkas. As I was recording the mazurkas, I remembered the tune, “Mominette” (by Maxou, in the tune book as untitled #26), which also goes to the IV chord at the B section and is quite lovely (especially as the A section has a ominous tone. Will things work out??? Yes, yes they will. You know because of the IV chord.)
Also, with the mazurkas, the first is a sans nom tune that I began to call “Hannibal’s Mazurka” some years ago (I was teaching the ancient Romans at the time). If anyone knows a different name, let me know. I can be taught!
