Welcome to David's Great Adventure, a digital impression of David Friedrich's life. In this binary version of a portfolio, David is going to tell you a little about his career, his life as a musician and composer, share about his experience and current work as a musicologist and media scientist, and exhibit how he has changed the world as a sound and media artist through his projects.

David was born in 1987 under the surname Teresa Carballo,  and was raised in a small town situated in the heart of Germany. In 2004, David started his career as musician, composer, and audio engineer followed by numerous concerts and studio recordings. In addition to his work as a musician, he completed his apprenticeship as a nurse in 2009 and worked on intensive care units in various hospitals between 2010 and 2018. David has dedicated himself to the research fields of musicology and media studies since 2015--making him the first in his working-class family with a migration background to study at a university. In 2018, he graduated with a bachelor's degree in musicology from Humboldt University of Berlin (Germany) and is currently part of the master's program for media studies at the same institution. Despite battling dyslexia, David was awarded the Humboldt-Scholarship (as part of the Germany Scholarship program) in 2020 for outstanding performance. Alongside his academic career, he invented the Theremin for the Deaf, the first musical instrument to produce sound without acoustics. From 2016-2019, David worked for the broadcast show Fritz Unsigned as a social media manager and as a freelance Radio-Journalist. He also designed the app Tour It Yourself, which enables musicians to book and manage concerts independently. Since 2020, David has been a co-organizer of TEDxHUBerlin, an independent and self-organized format of the worldwide renowned lecture and knowledge platform TED. Finally--and the most importantly--David has been the proud father of a spirited and hilarious daughter since 2014.
