Classics for Kids contains a wealth of music, musical games, lessons, and activities on composers and musicians from Baroque composers of the 1600s, such as Purcell, to Modern composers, such as Copeland and Bernstein.

There are brief biographies of composers, that include links to other composers who influenced them and who they influenced and links to excerpts from their music and the “Classics for Kids” radio show on Cincinnati Public Radio.  Biographies can be viewed by composer name, country, musical period, or by an interactive timeline.

Other activities include games for kids to compose their own music, a dictionary of musical terms and instruments, information about careers in music, and downloadable podcasts of the radio shows.  For teachers, there are elementary-based music lesson plans.

From site: Ear training develops and ties together all the skills that allow musicians to play, improvise and compose music by ear. It is the key to becoming not just good, but great. The ear training games on Theta Music Trainer will give you the practice you need without becoming monotonous or academic. Games inject an element of variety and fun into your practice routine and help boost your motivation. Basic musicianship skills are often best developed by working away from your instrument initially, in short bursts of concentrated practice. The games on this site are perfect for developing these skills, and are designed to provide a total workout of your musical ear and mind with as little as 10-15 minutes per day of regular playing.

Each game in the Theta Music Trainer is meant to train you in a specific area of musicianship. None of the games require that you read music or have prior training in music theory, but you will need to understand musical notation and also be ready to learn the fundamentals of music theory. All of the games start at the beginner level and progress gradually to more difficult levels.

Free Registration is required.
