HAMMOND ORGAN: (right) One of the most popular electronic organs, Ron’s Hammond was also used in his scoring of instructional and dissemination films during 1979 and 1980. Of the Hammond, he wrote: "This keyboard has a remarkable potential in altering the timbre of sound with its slides. One can actually even use those slides to separate a sound out or to prevent it from wiping." (see "Proportionate Sound")
