Calling Rampal "an indisputably major artist", "The New York Times" said "Rampal's popularity was grounded in qualities that won him consistent praise from critics and musicians in the first decades of his career: solid musicianship, technical command, uncanny breath control, and a distinctive tone that eschewed Romantic richness and warm vibrato in favor of clarity, radiance, focus and a wide palette of colorings. Younger flutists assiduously studied and tried to copy his approaches to tonguing, fingering, embouchure (the position of the lips on the mouthpiece) and breathing." Aside from his own recorded legacy, it was as much through his inspiration of other musicians that Rampal's contribution can be appreciated. Throughout the busiest years of his concert career, Rampal continued to find time to teach others, encouraging his students to listen not only to other flute players, but also to take inspiration from other great musical interpreters—be they pianists, violinists, or singers. He maintained a clear opinion about the right balance between "virtuosity" and aspiring to real musical expressiveness. "Of course," he said, "you have to master all the problems of technique to be free to express yourself through your instrument. You can have a big imagination and a big heart but you cannot express it without technique. But the first quality you must have to be good, to be inspiring, is the sound. Without the sound you cannot achieve anything. The tone, the sound, the sonorité is most important. Otherwise, with the fingers alone it is not enough... everyone these days has the fingers, the virtuosity... but the sound, the tone, that's not so easy." Following the foundation of the Nice Summer Academy in 1959, Rampal held classes there annually until 1977. In 1969 he succeeded Gaston Crunelle as flute professor at the Paris Conservatoire, a position he held until 1981. When 21-year-old James Galway sought Rampal out in Paris in the early 1960s, Galway felt that he was going to meet "the master". As Galway says in his own autobiography, "For me, of course, it was simply a sensation to meet this great musician; like a fiddler meeting Heifetz." Rampal took Galway along to the Paris Opera to watch him play, and, said Galway, inspired him rather than taught him on the occasions they were together. William Bennett, too, has commented on Rampal's infectious enthusiasm for music-making: "his repute came more from his musical sparkle and the happy personality which radiated to the audience".
