The DrumPhraseTraining app is a free Android app for learning drum sequences. From the main menu you can create a new sequence for which you can set the name, time signature, place notes on the tab (also triplets), delete notes from the tab, the tempo, save, see instructions and close the editor. The drum kit at the low part of the screen is used to place the notes on the tabs and the drum kit parts are: a kick, a crash, a ride, a snare, a hat, a china and 3 toms. The app can then use the set sequences to sound along with the percussionist. You can at anytime edit the sequences the same way you did wben you created them and also get information about the producer of the app. The app can be used on both tablets and phones, but requires a recent Android version and a real up-to-date processor. The DrumPhraseTraining app is a really well-constructed app that is a unique app in the store and offers all of its facilities, which are all great and functional, in the free version.
