what does it mean when there's a ' after a chord? like i saw Db'' today does it just mean two octaves up
if the lines are really big and slanted, it means the whole band stops and waits for something (pizza delivery? etc). if the marks are very tiny and it's hand written, i can only speculate that it actually says like -7 or something but they scribbled it too small. (?) or could be specks / flecks, of debris or other contaminatory substance
