Book Chapter 1: Theory And Harmony Part 1 Intervals Flashcards
Why are intervals so important in music?
They are the building blocks of polyphonic music
Define Polyphonic Music
The simultaneous combination of two or more tones or melodic lines
How must we memorize intervals
Each interval sounds different but also has a certain distance. We have to memorize them both audibly and visually
What do you call it when intervals are sounded together

What do we need to do to precisely identify intervals
We need to apply a generic classification to the interval (ex: 3rd, 2nd, 4th
What can we do once we apply a generic classification to the interval
We can give it a more precise description ( minor 3rd, Major 2nd, Augmented 4th)
Define an enharmonic interval and give an example
Intervals that contain the same equivalent numbers but have different names (G# and Ab)
