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 melodica, also known as the pianica, blow-organ, key-flute or key-ute, is a free-reed instrument similar to the melodion and harmonica. It has a musical keyboard on top, and is played by blowing air through a mouthpiece that fits into a hole in the side of the instrument. Pressing a key opens a hole, allowing air to flow through a reed. The keyboard is usually two or three octaves long. Melodicas are small, light, and portable.
