Hello! I recently started reading musical notational theory, and I know what exactly things say, but I am unsure what people mean by time signatures, for example, 4/4 time, or common time. I know that the top number denotes there are 4 beats per measure, but I have read many different definitions of what the bottom number, in this case 4, actually means. Most people say the bottom number tells you which kind of note gets "the" beat. Each beat is seperate, but it sounds like every beat gets several beats, to me! I don't truly understand this properly. ;\ Help? =P Example: The notes circled in red, here, are both sixteenth notes, but they have different amounts of ... bars attaching them. Does this alter their length?
