Our Music Reading Materials are not dependent on antiquated systems for identifying the Lines and Spaces on the Grand Staff. We've even suggested that students who wish to enroll in our studios and have learned things like Every Good Boy Does Fine or Elephants Get Big Dirty Feet, etc. may want to visit a hypnotist to have that information purged. A medical doctor explained the principle of "iatrogenices". Cures are suggested that produce additional problems. Using "sayings" to learn the names of the lines and spaces produces several additional problems that the MusicMaster™ Landmark System is able to avoid.
