Tapping is a guitar playing technique, where a string is fretted and set into vibration as part of a single motion of being pushed onto the fretboard, as opposed to the standard technique being fretted with one hand and picked with the other. It is similar to the technique of hammer-ons and pull-offs, but used in an extended way compared to them: hammer-ons would be performed by only the fretting hand, and in conjunction with conventionally picked notes; whereas tapping passages involve both hands and consist of only tapped, hammered and pulled notes. Tapping is used exclusively by some players (such as Stanley Jordan) and is standard on some instruments, such as the Chapman Stick.

Tapping may be performed either one-handed or two-handed. It is an extended technique, executed by using one hand to 'tap' the strings against the fingerboard, thus producing legato notes. Tapping usually incorporates pull-offs or hammer-ons as well, where the fingers of the left hand play a sequence of notes in synchronization with the tapping hand. For example, a right-handed guitarist might hammer down on fret twelve with the index finger of the right hand and, in the motion of removing that finger, pluck the same string already fretted at the eighth fret by the little finger of his/her left hand. This finger would be removed in the same way, pulling off to the fifth fret. Thus the three notes (E, C and A) are played in quick succession at relative ease to the player. It is often used on electric guitar but may be performed on almost any string instrument.

Louise Hay (born October 8, 1926) is an American motivational author, and the founder of Hay House, a publishing company. She has authored several New Thought self-help books, and is best known for her 1984 book, You Can Heal Your Life.

Hay recounted her life story in an interview with Mark Oppenheimer of the New York Times in May 2008. In it Hay stated that she was born in Los Angeles to a poor mother who remarried Louise’s violent stepfather. She recounted that when she was about 5, she was raped by a neighbor. At 15 she dropped out of high school without a diploma, became pregnant and, on her 16th birthday, gave up her newborn baby girl to be adopted. She then recalled she moved to Chicago, where she worked in low paying jobs. In 1950 she moved on again to New York. She explained that at this point she changed her name and began a career as a fashion model. She was successful at this, working for Bill Blass, Oleg Cassini and Pauline Trigère. In 1954 she married the English businessman Andrew Hay, but went on to tell how, after 14 years of marriage, she was devastated when he left her for another woman.

Bruce Harold Lipton (born October 21, 1944) is an American developmental biologist, who is best known for promoting the idea that genes and DNA can be manipulated by a person's beliefs. He teaches at the New Zealand College of Chiropractic.

Lipton was born in Mt. Kisco, an affluent town in New York. In 1966 he received a B.A. in Biology from C.W. Post Campus of Long Island University and then his PhD in developmental biology from the University of Virginia in 1971.

In 1973 he taught anatomy as an Assistant Professor at the University of Wisconsin School Of Medicine before coming to St. George's University School of Medicine, where he became a Professor of Anatomy for 3 years. From 1987 to 1992 he was involved in research at Penn State and Stanford University Medical Center. Since 1993 he has been teaching in non-tenure positions at different universities. His publications consist mainly of research on the development of muscle cells.

Lipton has appeared on several radio shows as well as The Elaine Smitha Show and The Joe Rogan Experience podcast episode 165.
