Super-complete summary~ all points of musical rhythm training are here
Beats are backbone of learning music, and for many people it's easy. However, if rhythm is not well learned, it will have a big impact on later learning, but this is easily overlooked.
Even if you're lazy, it doesn't matter if you really don't want to sum it up. Below is a very complete summary of beat knowledge and editor will help you~
Split 1 beat
The staves are separated by vertical lines, and spaces between lines are called measures. A bar contains several beats, and a typical piece of music may be tens or hundreds of bars long.
2 beats of perception
The beats are evenly distributed in these measures. The music is full of beats. Each note you hear lasts for a certain number of beats or beat parts. In general (excluding special cases):
Perhaps because most musical compositions have 4 beats per bar, each of them is called a quarter note.
3 longer notes
It would be too easy if composers could only use quarter notes as only rhythm. For a slight variation, composers came up with half notes. Apparently a variant of quarter note, half note lasts twice as long as quarter note. In standard 44-bar world, each half note takes up half a bar.
4 short notes
Some notes are shorter than a quarter note, such as an eighth note. In standard 44-bit world, length of each quarter note is equal to sum of lengths of two eighth notes.
Seeing triumph of eighth note, ancient composers quickly created faster notes such as sixteenth, thirty-second, sixty-fourth. To record these extremely short notes, composers came up with idea of adding more and more connecting lines or flags to them.
If you put a period after any type of annotation, it will be 50% longer. For example, a quarter note with a dot lasts one and a half measures. Pretty much all music you've ever heard is made up of note combinations that we've explained, and all rhythms are just long and short notes, creative combinations of long and short notes.
