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.
The time pattern controlling the change of harmonies is called harmonic rhythm. In 17th- and 18th-century music, harmony tends to limit rhythmic subtleties and flexibility of the melodic elements (as well as determining the basic type of melody) in regard to stress accents.
