The "Trumpet Fingering Chart" by Amsco Productions, is three-page wide chart, (24 3/4" x 11 3/4) which folds into thirds, (8 1/4 x 11 3/4). It is crisply printed on a high quality, plastic-type paper that should hold up to a lifetime of use, and can easily slip into a trumpet case. The fingering range goes from a low f# below the staff, to a high d natural above the staff. On the back side, the chart also provides information about notation, such as: Dotted Double Bars, First and Second Endings, D.C., D.C. al Fine, D.S., D.S. al Fine, D.S. al Coda, and more. It also includes information on taking care of your trumpet, such as: Putting the Instrument Together, Cleaning, Storing. If you are considering purchasing this Trumpet Fingering Chart, just do it! It's going to provide a lifetime of value for probably less than the cost of a bottle of valve oil. (R.I.P. Lloyd Higgerson, a great band director and trumpet player)
