Music is the artistic craft of arranging sounds in specific time intervals through the components of melody, pitch, texture, and rhythm. It's one of the most universal human characteristics-aesthetic, emotional, and communication. However, it's also one of the most misunderstood.
When you hear a song, you might think that it's just about the words, the instruments, or the coordination of notes and rhythms-but nothing could be further from the truth. Music has its own language, which can best be described as a gestalt, a'shape' or'shapely' quality. Each element of a melody or rhythm has a unique name, a sound, that comes after the root or 'name.'
To give a simple definition, Music consists of harmony. It's impossible for there to be more than one note or string on the instrument that creates the same balance in a composition. In other words, if two notes played together will not cancel out the others, then the entire composition itself cannot be considered melodic. This definition is very broad, however. Musical harmony occurs when there are no differences between notes or strings-and if any differences do exist, it is usually only at the lyrical level. Musical harmony occurs throughout a piece of music, not just in the lyrics.
Another way of looking at the idea of musical harmony is to consider it in terms of timbre, another word for harmony. If a song has an upbeat beat, the tempo of the musical elements is considered to be steady, while if the beat is slow, the tempo of the musical elements is considered to be fluid. The timbre of a melody is a matter of how well the different voices blend and mesh with each other. This aspect of musical flow helps bring out the quality in the melody that creates a unique quality in the overall composition.
Timbre is also a consideration because of its relationship to tone color. When two voices are singing in harmony together, they can vary the timbre of each voice without drastic alterations to their voices and their instruments. For instance, a piano roll that is played with a saw would have a slower timbre than the same roll played individually. There are limitations to the actual sound of the instrument, however, such as sharp or dull edges that may indicate different notes.
Musical tone colors and relationships can be introduced in compositions by changing certain melody components, such as tempo, melody type, and harmony. Changing the melody of a song without changing the harmony of the piece will change the listener's perception of tonal balance. Because of this, most composers will tend to write a variation on a monotone theme (or use a consistent tonality) in the background so that the melody and harmony are not compromised in any way. In other words, the overall musical goal is to create a composition that has a sense of unity regardless of whether or not the harmonic framework is consistent throughout the piece.
