This is a list of references of music and books or links to archives with clarinet related topics.
Books are still some of the best sources of information. They are the accumulation of years of research and experience. Many have been published long before the internet and their content is not available online. Nevertheless, they can be extremely helpful and a great source for inspiration. Many are available in libraries or can be ordered.
Some books might be written in a language you are not familiar with. Don't get discouraged! Luckily, modern technology makes it easy to scan whatever you are interested in and get it translated. Some books are available as E-books and can be translated directly on your device. They might not always be 100% accurate but these programs improve rapidly.
