Music is the greatest communication in the world. Even if people don’t understand the language that you’re singing in, they still know good music when they hear it. We are all aware that music and « atmosphere » go together. We might put on relaxing music for a quiet romantic dinner, but listen to something livelier while doing some physical work or exercise or when out socializing in larger groups. You might have heard of farmers who increase production by playing music to their animals. Recent studies showing that listening to fast music while driving increases the rate of car accidents and the Mozart Effect claims to increase intelligence. While some claims may be exaggerated, there is no denying that music can be suggestive and affect our state of mind. But the reason for this is very mysterious. Pitch Melody and HarmonyTempo and Rhythm and its combination has an immediate physical impact on our perceptions. The rhythm of an object suggests more or less frequent movement to qualify the repetitive nature of the underlying beat, even though the tempo of a piece of music might be slow and relaxed. A high frequency of notes can suggest a degree of contained excitement within that relaxed state. Tempo & RhythmMusic tends to have a steady tempo to it, often measured in beats per minute. Most of the music based on simple observation is in the range of 50-200 beats per minute, the same as the extreme range of our heartbeats. The music tempo of the piece of music roughly equates with the heartbeat associated with the corresponding state or emotions. Music, at its essence, is what gives us memories. And the longer a song has existed in our lives, the more memories we have of it. A good melody (even if it doesn’t have words) is often one that we could hum, sing or whistle. Generally melody consists of a linear sequence of tones. The notes should have durations which are not too short and not too long, and should not be in an extreme range or shouldn’t have large awkward jumps between them. Although instrumental musical can stretch those boundaries a little, melodies in its way are very similar to sentences that our brains are designed to speak and listen to.
