The Meaning of 8 in Music
In music notation, the number 8 is often used to indicate an octave shift. When an "8" is placed below or above a clef, it means that the pitches should be played one octave lower or higher, respectively, than they are notated. This is known as an "ottava" or "8va" line.
For example, if a treble clef has an "8" below it, the pitches should be played one octave lower than written. Conversely, if a bass clef has an "8" above it, the pitches should be played one octave higher than written. This is a common notation used in music for guitar or tenor voice.
It's important to note that the number 8 can also have other meanings in music, depending on the context. For example, it can represent a time signature, such as 6/8, which indicates a compound meter where the pulse is felt in groups of three beats.
Overall, the meaning of 8 in music notation primarily refers to an octave shift, indicating that the pitches should be played one octave higher or lower than notated
