Omitting symbols is to simplify the symbols used in notation. These include:

1. Octave symbols (including octave movement symbols and octave repetition symbols)

2. Octave movement symbols: use the numbers 8 or 8va, etc. plus a dotted line. If the mark is recorded above the note, it is called an octave higher. On the contrary, if it is marked below the note, it is an octave lower.

3. The octave repetition mark is marked with con8 and a dotted line. It is recorded above the note. It must be played an octave higher than it at the same time, otherwise it is an octave lower. If it is an octave repetition of an individual note, Represented by only one number 8.

4. Repeat marks, that is, repetition at the beginning, repetition at paragraphs, etc. Just remember that D.C means starting from the beginning, D and S means repeating from the mark. There are also sound pattern repetition marks (two slashes) 5> Tremolo marks: those marked with slashes are homophonic repetitions 6. Free repetition. This mark can be repeated many times. 7. Long rest mark: The mark written on the third line of the staff is the mark of -------, which is the long rest mark.

There are only five commonly used musical symbols: whole notes, half notes, Quarter notes, eighth notes, and sixteenth notes. Others are not commonly used, so beginners don’t need to learn them yet. Concept: (one point two, two points four, four points eight, eight points sixteen). For example: one whole note equals two half notes. One half note is equal to two quarter notes. One quarter note is equal to two eighth notes. One eighth note is equal to two sixteenth notes, etc.

The notation of simplified musical notation is: whole note: there are three short horizontal lines after the number. Half note: There is a dash after the number. Quarter Note: Only one number is remembered. Eighth note: There is a dash under the number. Sixteenth note: There are two dashes under the number.
