How much carbon dioxide per mile is produced by the average gasoline car vs. a coal-powered electric car? I'm looking for overall carbon footprint based on pollution at the power plant and pollution by the car.
A harmonic interval results if the notes are played at the same time, whereas a melodic interval occurs when the notes are successively. If they are playing more than one note at a time then it is harmonic or has harmony. If they are playing one note at a time then its melodic or a melody.
Melodies can interact a number of different ways, so there are several broad terms that describe the different kinds of textures based solely on melody. Monophony is the texture comprised of one-and only one-melody. Polyphony is the texture comprised of more than one melody, and Heterophony is the texture of the same melody played in different parts in slightly different ways. Call and Response is made up of two different melodies in alternation.
