The interval of an octave is essential in music as it allows us to structure our perception of notes in space. On a piano keyboard, the range typically extends over 7 octaves, from low to high register.
Goals
In this exercise, you will hear identical musical sequences played in three different octave ranges: low, medium, and high. This will help you identify octaves when you hear them in a piece of music.
Tips for success
Remember to rely on your perception: The low octave sounds deep, heavy, and powerful. The middle octave is balanced and central. The high octave seems light, bright, and crystalline.
