How do you write an octave higher show an example?

To write an octave higher, you simply transpose the notes up by eight scale degrees. For example, if you have a C note in the bass clef, you would move it to the C note in the treble clef, which is one octave higher. In terms of notation, if you start with the note C4 (middle C), an octave higher would be C5. This can be represented as: C4 → C5.
