I'm learning Clair de Lune, and I'm a bit stuck on measures 25 & 26 as well as general questions.I'm a relative beginner at music, so I'll start with the time signature: 9/8, I understand this means that there are 9 beats per measure, and that one beat is a quaver, so does that mean a crotchet is 2 beats, a minim 4, etc?Secondly, if you have a flat in the key signature and before the note, is that a double flat? So is it a whole step down?Thirdly I don't think my hand is big enough, to play all of the notes, so should I drop a note? Thanks.
