My question concerns this short piece of music: http://czteryrefy.pl/data/dskgrtx/teksty/nuty/pressgang.html The key signature has 3 flat signs. But there is no actual A♭ sound in the song because all the A♭ have an accidental ♮. My questions:
- What is the key of this song? Is it c-minor? Is it a mode?
- Could this song's notation be simplified by having only 2 flats as its key signature and no accidentals?
