I met a minstrel in Lions Arch
I don’t know if it actually was a song or not because flute generally doesn’t mix well with harp. Harp is in C and Flute is in E, they can only cross for flute notes that aren’t semitones. The flute sequence would have to be 4 5 1 8 (A, B, E, E (octave higher) ) or it would never mix well. The harp chords could be anything that contains one of those notes.
If they come on and comment what song they played then sweet.
near the end sounds like musician’s guild of tyria
