From the foreword of this massive 160+ page collection for trumpet (with or without piano) and playable as solos or duets compiled by Dan J. Royal:

In this volume, as well as in companion volumes, the editor has selected a great variety of popular material to provide something for every taste.

The book is planned to provide enjoyable playing for recreation, but is also highly valuable as an educational supplement to the usual instrumental method

The arrangements have been made so that in addition to solo use with piano accompaniment, they may be used as duets with mixed groups of like or unlike instruments.

In the arranging, technical difficulties have been reduced to a minimum to make the music suitable for young players of limited experience as well as adult musicians who play only occasionally as a leisure activity.
