Music is the art of composing sounds in specific sequence in time to create a melody through the components of harmony, rhythm, timbre, and melody. In music, a basic unit of time is called a beat. It can be used to express emotion in music. It is among the universal cultural traditions of all human cultures.
The major premise on which music is built is that of establishing a formal structure by means of melodic or rhythmic phrases in harmony with each other and by the arrangement of their beats in the score. In this way, the music expresses a certain mood or idea. A typical musical theme or movement might be expressed by a series of beats per minute called a measure. The first note of each measure is a leading beat. Every measure thereafter has a succeeding beat as a bass beat, a treble beat, and an octave beat.
Music has three main categories-the major scale, the minor scale, and the chromatic scale. The major scale has a single note and a different pattern of beats than the other two. It may contain one, two, or four notes. It usually begins and ends in the same key. When it contains more than two notes, the melody is usually put together by means of a form of repeated parallelism a type of rhythmic construction in which each note of a pattern moves in exactly the same way as another note in the same pattern.
Rhythm is expressed by the use of polyphonic music forms which consist of many tones in one section of the music. The clef, which marks the beginning and end of a measure, can be made up of one, two, or four notes depending on the rhythm of the piece. This clef is often called the pulse. The most familiar example of a polyphonic clef is the opening lines of Beethoven’s Fifth Symphony. For a similar effect, one can listen to some jazz.
While the clef and the rhythm have a place in music composition, they are two very different concepts and can not be considered synonymous. The difference between the two is often described using what is known as the metronome. A metronome can be defined as a device that indicates the beat of the piece (sometimes called the tempo) and aids the musician in timing their own parts to that tempo. In relation to music teaching, metronome can also indicate the degree of variation in tempo, a characteristic not found in the clef.
Another difference between the clef and the rhythm is that the melody has no beat, but rather is expressed by repeated chord progressions. This beats per minute, or BPM, is what is used to determine the level of intimacy or interest in a piece of music. The most commonly used, popular, and best-known BPMs are found in rock music, pop music, and country music. These styles tend to use faster tempos with sharp, sharply contrasting lines. In the case of a melody, the tempo can move faster, but not infinitely, which makes for an unstable listening experience.
