Metheny was born in Lee's Summit, Missouri. His father Dave played trumpet, his mother Lois sang, and his maternal grandfather Delmar was a professional trumpeter. Metheny's first instrument was trumpet, which he was taught by his brother, Mike. His brother, father, and grandfather played trios together at home. His parents were fans of Glenn Miller and swing music. They took Metheny to concerts to hear Clark Terry and Doc Severinsen, but they had little respect for guitar. Metheny's interest in guitar increased around 1964 when he saw the Beatles perform on TV. For his 12th birthday, his parents allowed him to buy a guitar, which was a Gibson ES-140 3/4.
