The Perpetual Motion is the first song in the Suzuki books to incorporate the fourth finger. When you play fourth finger it will be the same note as the open string to the right e.g. 4th finger on the open A string is the same note as the open E string.

Good areas to review before learning to use fourth finger:

- Keep left fingers curved and knuckles flat. Fingers should be bent at all joints.

- Left pinkie should be relaxed and hovered over the fingerboard like the other fingers. Never keep it curled inward toward your palm when playing. If the pinkie tightens and curls, there are some good exercises to help keep it relaxed to keep it over the fingerboard.  This will also help keep you entire hand from being tense, and will not feel tired after a short amount of time.

- The left arm should be under the violin and palm should face you. You will hear me say over again “come around!” which means to get your elbow more in front. This will help reach the fourth finger more easily.

*When you play with the fourth finger, it will at first may seem like a stretch. Just remember to keep the pinkie curved and it will eventually feel less weak with practice.

The Suzuki Book I has a good 4th finger exercise with the Perpetual Motion which I always like to use with my students. It lets you play first with open E and then try to match the note with fourth finger.
