To create a framework for my research I wrote a series of questions which have over time, produced further areas of research for future discovery. After looking through my initial questions it became clear that I should reduce and refine my study so as to keep the focus on the performance aspect of the research. Many of the original questions, considered too far outside the focus of the main study, can be found in the Background Research section.
Other authors and musicians have carried out investigations into the keyed trumpet, notably Reine Dahlqvist and Edward Tarr. With their discoveries in mind, I decided to reduce the amount of academic research I was doing and concentrate on the practical areas that have not been fully explored by others.
