The Learning Music site describes and explains important musical concepts that are the building blocks of inspirational sound. I really enjoyed the hands-on learning tools such as, backbeat that is any rhythm sound in music that puts emphasis on the second and fourth beats in a bar. Backbeats come in all shapes and sizes and can be heard across just about any genre from country to rock to hip-hop.
Furthermore, a beat is a main accent or rhythmic unit in music or poetry. In music theory, the beat is the basic unit of time, the pulse, of mensural level. The beat is often defined as the numbers a musician counts while performing. In popular use, beat can refer to a variety of related concepts including pulse, tempo, meter, rhythm and groove. These concepts are a foundation of sound that we would refer to music. The learning Music site is a helpful tool that allows you find your own rhythm.
