Thanks & References
Creating new works is only possible by basing on previous work from other people.
Tools
I want to thank the Lilypond Project for creating and maintaining a really great music engraving tool. All my scores are written using this tool (and the source files with the ".ly" file extension are usually provided along with the PDFs).
Inspirations & recommendations
- The King's Singers, the famous a cappella ensemble from Great Britain, known for their huge repertoire and their perfect sound and intonation
- Out of the blue – Oxford University's male a cappella group, YouTube Channel
- The Choral public domain library, which provides lots of free to use sheet music.
