The school is designed for adults and teenagers from 14 years old and starts from scratch, so no previous knowledge is necessary. The school is designed for 1 year and is divided into 12 lessons, so each month the student can see if he is progressing well or if he needs to do more. In each lesson there is theoretical information that conveys knowledge and practical exercises and songs, trying to link the two parts as closely as possible.
The theoretical section can be divided into information on practicing, wind technical background and explanation of musical expressions. Since this school is also suitable for self-study, much emphasis is placed on information and tips on practicing to ensure independent progress of students. Since adults are very cognitive learners, all topics that are important for a beginner trumpet player are addressed and explained in an understandable way. In this way, the student not only learns to get notes out of the instrument, but also understands connections and can help himself and optimize his practicing and playing. A new, field-tested textbook in the well-known 'hobby series'.
