Sixty-fourth note: /photo/m4xR1qsJOXVhSFRmQkjioA==/4239013149263765559.jpg.
In fact, there are many kinds of notes, so I won’t list them all.
It is useless to look at pictures for this kind of thing. You should read books: /view/eefa4d94dd88d0d233d46a14.html;
/view/8137cdbff121dd36a32d8216.html;
In these books They all talked about musical notes.
Ask me if there is anything you don’t understand. :)
