Full Informative Speech: How to Buy a Guitar by Richard Garza
Richard does a good job of considering the age range, experience, and interests of his audience. His quote from the radio, use of humor, and guitar playing make for a comfortable and familiar introduction. The students in his class are likely to share his image of guitars and guitar players, and to recognize the Led Zeppelin songs he's chosen to play.
Richard uses the idea, heard on the radio, that playing guitars could lead to stardom. He refutes the idea with a bit of humor but shows by his playing that he is an accomplished guitar player, thereby establishing authority.
Citing guitar magazines supplements Richard's authority. The quote from Guitar Player magazine enhances Richard's credibility with the advice of a published expert. Richard demonstrates his knowledge while he quotes the magazine.
Richard also uses examples from his own experience and from his research to demonstrate and describe the process of carefully choosing a guitar.
By playing his guitar, Richard simultaneously shows his competence and heightens the audience's interest. The long period of time he spends playing in this introduction, however, might be somewhat distracting.
Before moving into the body of his speech, the speaker previews his main points.
In his conclusion, the speaker effectively echoes three parts of the introduction: the "road to fame" radio comment, his guitar playing, and the Led Zeppelin song.
Overall, Richard's delivery indicates a heightened degree of anxiety. He seems somewhat uncertain about how to use his hands and arms. Also, his rate of speaking is a bit too fast, as are some of his transitions between subpoints.
Richard makes good use of humor to illustrate how preconceptions about a guitar's appearance play into guitar selection.
Many audience members will find his repetitive use of "this one right here" and "this here" distracting. This phrasing is sloppy and imprecise. "This guitar" or "my guitar" are more concise and efficient phrases.
Richard uses his own instrument as a visual aid to show the benefit of carefully choosing a guitar. The guitar is in very good condition, and his revelation that it is twelve-years-old helps to establish him as an expert.
Richard uses the magazine he discusses as a visual aid. Correctly, he only keeps it visible for as long as is necessary to show it.
