The European Real Book
These aren't major hitches and any reasonably intelligent person will eventually figure things out, but it's an unnecessary part of the learning curve. To its credit, most of the supplemental aspects of the are well presented, including an opening two-page spread covering music basics and nearly 80 chord variations.
Obviously The European Real Book isn't likely to be anyone's ideal first fakebook, but it may be the best second choice for many jazz players not seeking a specific collection such as Latin or Broadway tunes. A collection of modern U.S. compositions is still sorely lacking, but this fills much of that gap in terms of presenting current styles and thinking, while offering additional insight thanks to the musical accents of artists in a range of countries.
