"Tonight, the bottle let me down." Music. Stop reading and hear it play. One from your day, today. "Tonight, the bottle let me down."
In discerning from the realms an understanding of the music in time, the equation is tested, means by spirit, of addition, to the lyrics if added. Musica, in itself, is on it's ownstanding, however, it is the addition of verbal communication which begins the span of human opinion. The melody of all things Man are, in themselves, great works of orchestra: the guitar, electricity, the operation of the machine (the engine).
Therefore, in the instances of music, the patterns are swayed to positive or negative by the simple word of lyric. An experiance positive/negative.
