Know Your Cello Strings Teacher Manual simply introduces the four strings of the cello and standard rhythms that you will find throughout music as your sight-reading becomes 'second nature'. Each string is given a color and character to make the sound of the string unique and identifiable to the beginner. At this point we are establishing sight-reading skills and ear training. The 'red alligator' for the A String, a 'gray dancing dog' for the D String, a 'green giraffe' for the G String, and a 'chocolate candy cane' for the C String.
