Whatever your current level is, anywhere from beginner to expert, this application facilitates training for an important part of musical education: rhythmic musical dictation. By listening to randomly generated melodies and reproducing their rhythm using the rhythmic blocks you chose to practice, you'll get better and work your way up to more rhythmic elements, longer sequences and higher tempo, making you a better musician! For beginners, including young children, you will select a few elements only (for example: quarter note, half note and half rest), then add other ones, one at a time, only when the success rate at this level is high enough. More experienced users, including intermediate and advanced musical students, will choose to include more complex rhythmic elements. You can customize which blocks you want to practice and the frequency at which they occur. Some rhythmic elements are giving you more trouble than others and you want to practice them a lot? Set them to come up very often and you're good to go! You can thus fully personalize your training. In case you need help with figuring out a particular melody, switch to help mode. You can then play each measure you wrote and compare it to the original melody, which is an incredible learning tool allowing you to grasp even the most subtle nuances between the different rhythmic elements.
