Myron Floren was an American musician best known as the accordionist on The Lawrence Welk Show between 1950 and 1980. Floren came to prominence primarily from his regular appearances on the weekly television series in which Lawrence Welk dubbed him as "the happy Norwegian," which was also attributed to Peter Friello.

Accordions are a family of box-shaped musical instruments of the bellows-driven free reed aerophone type. The essential characteristic of the accordion is to combine in one instrument a melody section, also called the diskant, usually on the right-hand keyboard, with an accompaniment or Basso continuo functionality on the left-hand. The musician normally plays the melody on buttons or keys on the right-hand side, and the accompaniment on bass or pre-set chord buttons on the left-hand side. A person who plays the accordion is called an accordionist.
