Music lessons are a type of formal instruction in playing a musical instrument or singing. Typically, a student taking music lessons meets a music teacher for one-on-one training sessions ranging from 30 minutes to one hour in length over a period of weeks or years. For vocal lessons, teachers show students how to sit or stand and breathe, and how to position the head, chest, and mouth for good vocal tone. For instrument lessons, teachers show students how to sit or stand with the instrument, how to hold the instrument, and how to manipulate the fingers and other body parts to produce tones and sounds from the instrument

The guitar is a plucked string instrument, usually played with fingers or a pick. The guitar consists of a body with a rigid neck to which the strings, generally six in number, are attached. Guitars are traditionally constructed of various woods and strung with animal gut or, more recently, with either nylon or steel strings.
