Question

how high or low note is
the loudness of a note
the length of the note
the range of notes in composition

Answer 1

The frequency of a note determines how high or low it is. The higher the frequency, the higher the note; the lower the frequency, the lower the note.

Loudness, on the other hand, is determined by the amplitude of the sound wave. A note with a higher amplitude will be perceived as louder, while a note with a lower amplitude will be softer.

The length of a note refers to its duration or how long it lasts. Notes can be short or long, depending on the notation used in the composition. The duration of a note can vary from very short (a thirty-second note) to very long (a whole note).

The range of notes in a composition refers to the span or distance between the highest and lowest pitches used in the piece. A composition can have a wide range, covering a large span of notes, or a narrow range, with a limited number of notes used. The range varies depending on the composer's intentions and the style of the music.
