|At winter NAMM 2001 Yamaha introduced their next
generation of solid silver flutes with the 600 and 700 series aiming at
the amateur and professional alike. The four main models YFL-674H/684H/774H/784H
are available in a number of variations. The 600 series, with silver-plated
keys, and the 700 series, with solid silver keys, both combine Yamaha quality
with several updated features.
The most notable improvement to these models is the Type 4 body, previously available only on custom 800 series flutes. Designed with the orchestral player in mind, the Type 4 body was created to maintain a focused tone in every range, at any dynamic level. These new flutes feature an innovative tonehole design to provide precisely the right amount of air resistance for tone color flexibility.
The EC cut headjoints, bodies and footjoints are solid silver on each flute, and the keys on each are French-style with white gold springs. The 600 and 700 series models are available with either the traditional inline G (YFL-684H/784H) or offset G with the split E mechanism (YFL-674H/774H). The split E mechanism allows for a smooth, in-tune high E. This feature, common on the higher-priced 800 series, is now available on the more affordable 600 and 700 series flutes.
For the European market the 600 and 700 series flutes were launched at Musikmesse Frankfurt 2000.
