This is the first book of its kind What began as a fun activity for my trumpet students has turned into a wonderful resource to improve their trumpet playing. Trumpet Folk Fill in the Blank is a book of thirty folk songs and nursery rhymes. Each song is presented first in an easy key, like C, F or G. Then it is transposed to other keys and certain strategic notes are left out. Those notes are replaced by question marks. The students are to practice the first version of the song until they get the sound of the melody in their ears. After they master the first version, then they are ready to play the "fill in the blank" versions of the songs in other keys. We use a total of seven key signatures in this book, up to three flats and three sharps. Any student who knows their scales up to three flats and three sharps should have a lot of fun playing these "fill in the blank" songs. Benefits of playing the "fill in the blank" songs include ear training, finger technique, sight reading, phrasing and tone.
