There are a couple of small errors in the LilyPond section of the Musician's Guide. Section 12.4.7, last example: The explanation following the code example refers to a "violin" section, but in the code the section being referred to is actually called "something". In the example, the variable "something" should be renamed to "violin" to match with the explanation. Section 12.4.8.2, second example: The guide states: "The first bar has four half-notes, which is twice as many beats as are allowed. LilyPond will print a warning at the first bar-check symbol." This is incorrect. The first bar-check will align with the second bar line and thus not produce any warning. The guide's interpretation of the bar-check symbol implies that you would have to put a bar-check at the end of every measure, which is not the case. The example should be modified so that it will actually produce a warning. A good example is "\time 4/4 c4 c2 c | c4 c2 c4 |" (in this hypothetical scenario, the third pitch's duration was mistakenly omitted, causing the bar-checks to fail.)
I have inspected the document, and see that you're quite right about these errors. My schedule is full for a few weeks, but I will make changes in December, and post here to let you see an updated version. The corrections will be released with Fedora 15. Thank you for your help in improving Fedora's documentation! We welcome further feedback as a response to this bug.
