Tap along with basic Salsa patterns and improve your command of clave: You can pick a pattern and learn to tap it out together with clave. Now, flip hands and master it that way as well. You will feel how clave works with your pattern, and have a better understanding of how your part fits. Why this app: Salsa music really begins to make sense when you know how the patterns of the various instruments go together. This app was built with this in mind! Clave Master allows you to easily choose a pattern by tapping on the music staff or by long-pressing the tap pads. Choose "None" on one thumb to get a single pattern mastered, then up the ante by adding a different pattern to the other tap pad! Start at a slow tempo, work diligently to learn the patterns against one another, and you will gain a deep understanding of how the patterns in salsa music function together. You will dance better, you will play better, and you will begin to FEEL the clave!
