Final answer:
A melody that seems complete is called a tune, created by combining musical notes with specific names which evoke emotions. The uniqueness of each note stems from an instrument's distinctive timbre, and rhythm and harmony are key elements that contribute to the expression of music.
Step-by-step explanation:
A melody that seems complete in itself is commonly referred to as a tune. In music, a tune is a sequence of musical notes that are perceived as a single entity. It usually possesses a memorable series of pitches and rhythms that conveys a musical thought, an idea, or a particular mood.
Musical notes are the basic units of music and have specific names like A-sharp, C, or E-flat. When these notes are combined skillfully, they can create tunes that evoke different emotions. The ability to identify musical notes by ear is known as perfect pitch, which is a rare skill. Furthermore, each musical note played on different instruments will sound unique due to the specific timbre of the instrument, which refers to the character or quality of the sound that makes it distinct.
Rhythm plays a crucial role in forming a tune as it gives music its flow and movement. When combined with harmony, which involves the simultaneous combination of notes, it creates a fuller musical experience. Some forms of music may rely solely on rhythm or harmony, while others use both to express character, emotion, and action.
