I am like a melody. A melody is an arrangement of sounds that makes up a musical piece. It is considered the foreground to the background. No one wants to listen to a song that doesn’t have a nice melody.

(from Greek μελῳδία, melōidía, "singing, chanting"),[1] also tune, voice, or line, is a linear succession of musical tones that the listener perceives as a single entity. In its most literal sense, a melody is a combination of pitch and rhythm, while more figuratively, the term can include successions of other musical elements such as tonal color. It may be considered the foreground to the background accompaniment. A line or part need not be a foreground melody. Melodies often consist of one or more musical phrases or motifs, and are usually repeated throughout a song or piece in various forms. Melodies may also be described by their melodic motion or the pitches or the intervals between pitches (predominantly conjunct or disjunct or with further restrictions), pitch range, tension and release, continuity and coherence, cadence, and shape.
A melody is a group of rhythmic tones. A pleasing arrangement of sounds. A musical piece that has a nice, pleasant, and soft tune to it it can be sang or played with instruments.

A rhythmically organized sequence of single tones so related to one another as to make up a particular phrase or idea

A melody can be a song in your heart. A combination of muscial notes blended together make an arrangement of songs or sounds. Most time very pleasing to the ear.
Melody is affected by its tempo -- when it is played smoothly, this is called "legato." Short, sharp notes are called "staccato" while very short notes called "spiccato" are played by stringed instruments.
A good melody, like a good house, has a solid basic framework. This is then embellished and refined to create more interest. When creating a melody, composers often start with a rhythmically simple line according to the following guidelines, then add the embellishments later. A full understanding of common practice melodic guidelines is essential for writing and understanding these melodies
For a melody to really work, it has to have some degree of repetition.
Melodies can make you happy, sad, anxious, a feeling of power, angry, and can even make you cry
