ideas. They are basically the same things as lines, but they are shorter. Phrasing Phrasing is a very important part of jazz players' set of improvisational skills. Instead of just playing a sequence of scale and chord notes that would work based on the chords, harmony, etc., the player builds an idea based on a melodic motif or a rhythmic motif. The player in effect extemporizes a new melody for a tune's chord progression. Alto saxophonist Charlie Parker, who is considered to be an exemplar of jazz improvisation, paid special attention to the beginning and ending of his solos where he placed signature patterns that he developed over the years. The middle part of his solos used more extemporaneous material that was created in the moment. This shows a developed style of musical phrasing where the shape of the melody has a logical conclusion. With his strong beginning, Parker was free to create solos that demonstrated musical phrasing, and led to a logical and memorable conclusion. Examples of this motif-based approach in a compositional context are found in classical music. In Beethoven's fifth symphony, the first rhythmic and melodic idea is played again with many variations. The social dimension Jazz improvisation includes a multitude of social protocols for which the musicians have to adhere to. However, "there is no Emily Post handbook for these protocols, but people who drink in the culture of jazz learn what these conventions are." There are no strict rules, but rather general social protocols that guide the players through when to begin their improvisational solo and when to end. These social protocols also tell the player vaguely what to solo about, for example it is a nice gesture to take parts or an end of the pervious musician's solo to then incorporate into the new improviser's solo. For beginning jazz listeners, it can be difficult to understand the structure of a jazz solo and how it fits into the overall song. It may take some time for a listener to even recognize that there is a distinct format for solos in jazz music. Additionally, understanding the role of improvisation in jazz can be challenging to gain from just listening alone, which is why seasoned listeners may be able to recognize solos and formats after "drinking in the culture of jazz" for a longer period of time, therefore, the superficial aspect of a jazz solo is
