This is a rudiments training application supervised by an active drum instructor. (There are other accent exercises in addition to this, and we will continue to expand our practice content!) This app contains 39 of the 40 international drum rudiments, excluding "multiple bounce rolls". You can practice and learn the rudiments while listening to the samples as well as the sheet music. [Features of this app] The BPM of each rudiment you practice is recorded even when the app is closed, so you can challenge yourself from your limits the next time you open the app. It takes time to improve your skills, but you will feel your growth every day as you climb the stairs step by step. [Practice Tips] First, create a beautiful form at the slowest tempo. Once the form is finalized, increase the BPM by 1. Repeat this process and you will have a beautiful and fast stick control.
