There are three different types of rock music, alternative rock, classic rock, and hard rock, also known as metal. Alternative rock features a steady bass drum laying down the beat, with easy flowing guitar riffs over the top. The bass line is toned town, and the lyrics are sung with intensity an authority. Depending on the song, the guitars can either be acoustic guitars or electric guitars. Classic rock combines a steady driving bass drum sound, with high snare overtones, steady and often repeating guitar riffs, and an intensive bass line. The guitars are more often than not all electric guitars, and distortion is rarely used. The lyrics are sung with style and enthusiasm. Hard rock, or metal, features a hard rolling bass drum with an abundant amount of cymbal work. This style of rock uses several electric guitars with heavy distortion to bring a very intense sound. A hard, intense, driving bass line rounds out the style. The lyrics aren’t really sung so much as screamed. It doesn’t matter what your preference is, each different style of rock music is unique on its own.
