No, I do not normally charge anything extra for lyrics. I am fluent in German and Russian, so this doesn't slow me down much. However, please write for an estimate regarding any other language. If the lyrics are easily legible, I will not charge extra for their inclusion.
If there are fingerings involved in your project, we must make a distinction and come to an agreement as to whether they are to be considered extensive or not. Try me! Many are surprised as to how lenient my system of evaluation is! I will not charge extra if the fingerings are not extensive.
Because of the vast amount of variety in the different requirements of projects, it is too difficult to state whether all formats can be offered for the said price. This mainly concerns the formatting of publications such as musicological studies and avant-garde music. If you have a project which is atypical in any manner, please feel free to write with your hopes, wishes, and expectations. I am always willing to take on a challenge!
