Under the title of “4stringboy” Sammy is an award winning ukulele virtuoso, combining ambient composition with a modern style of solo playing using harmonics and fingerstyle techniques.
Sammy has gained a name for himself as a “magician of harmonics” and has been featured on The Ukulele Site and Ukulele Underground podcasts.

Sammy is a Flight ukulele artist and a proud endorser of Ukelogic strings, and has collaborated with Blackstar, Soundbrenner, Roadie, Mono and Openhagen.

As a teacher of many years, Sammy still keeps his love of being an educator by teaching ukulele online through his Patreon, website and private lessons. His Instagram following started growing after the creation of his own weekly fingerstyle tutorials #fingerstylefursday, which combined beautiful composition with fundamental technique and core skills necessary for improving players.

In 2023 Sammy released his debut album VEJR (weather in Danish) which is a ukulele led album of moody, ambient compositions all about the weather, challenging what a ukulele can do and is known for.
