I have been trying to pick up the piano and have a few questions concerning accidentals and key signature placement and interaction.
I apologize I don't have a digital copy of the music in question and don't quite understand all the lingo yet but bear with me:
I have accidentals placed immediately after the treble clef. I understand these apply to the entire song. A few measures in, there is text above the measure, that says Eb, which I believe is changing the key signature to the Eb one (I found a chart online that helps). I have a few questions now.
1) I see no naturals on that measure. Do the 'Eb measure' flats compliment the original flats found next to the Treble clef that I understood to apply to the entire song? Or do the Eb measure flats now take precedent over the original Treble clef notes, and I am to ignore those. 2) If they indeed compliment each other, if there is some overlap, i.e. an D is flatted on the original treble clef, and also in the key signature for that measure, do we call that a double flat and it's just one key lower, or that D has effectively just one flat with some redundancy? 3) To make it more challenging on me, the music proceeds to change key signatures yet again around measure 7. Does that key signature in a latter measure overwrite the Eb flats that were specified in a key signature few measures before?
I'm wondering if they are indeed additive, the majority of the song will be all flats by the end which doesn't seem right.
