Brass Up is a free iPhone app developed by David Marques that offers a unique way to practice and improve your skills on valve brass instruments. Whether you play the trumpet, euphonium, baritone, tuba, or french horn, this app has got you covered.

With Brass Up, you can simulate fingerings for most of the valve brass instruments in any of the 12 keys. The app presents random notes in the selected key, allowing you to practice fingerings and improve your dexterity. Additionally, you can choose to practice scales or Arban-style exercises to further enhance your skills.

Brass Up features two modes: Learn mode and Drill mode. In Learn mode, the app shows you the fingerings for each note, helping you learn and memorize them. In Drill mode, you can put your skills to the test by practicing without any visual aids.

For quick reference, Brass Up includes a lookup feature that allows you to find the fingerings for all notes in all 12 keys. The app also supports alternate fingerings, providing you with more flexibility and allowing you to explore different techniques.

Whether you're a beginner or an experienced player, Brass Up is a valuable tool for improving your valve brass instrument skills. Download it now and take your playing to the next level.
