You can play harmony on the ukulele by clicking the F and Dm or by using F and D on your keyboard. Just play a steady beat along with the song. F will play during the April showers verses. Dm will play during the Thunder lightning verses. You can also play part of the melody on a xylophone. Use your number keys to play "April showers bring May flowers" and "Thunder lightning very frightening".
The song is an original I composed to help my students compare major and minor harmony and ABA form.
