Thank you for purchasing a YAMAHA concert marimbas.
Exhaustive research by Yamaha technicians and craftsmen focusing
on tone quality and playability, has led to the design and creation of
these marimbas, using select, high quality materials, and Yamaha's
original FRP Acoustalon. We are convinced that you will enjoy play-
ing your instrument that produces spreading and yet deep sounds as
well as rich volume to your content.
This manual describes proper use of YAMAHA concert marimbas.
Please read it thoroughly to ensure that your instrument will give you
enjoyment for a long time.
1. High-Quality Tone Bars
Tone bars are made of rosewood, which delivers an
ideal marimba tone and timbre, and African padauk,
which offers a rich sound that is soft and deep. After
allowing the woods to dry naturally over time, only
the finest select pieces are selected for use in mak-
ing the tone bars.
Type F models use Yamaha's FRP Acoustalon tone
bars that have a unique semi-hollow design. These
bars deliver a clear sound that is extremely close to
the sound produced by high-quality rosewood. It of-
fers excellent projection, and full volume. Compared
to wood tone bars, Acoustalon is highly weather re-
sistant, being little affected by changes in tempera-
ture and humidity, which can alter the pitch.
2. Fine Tuning
Tone bars are tuned by the highly refined ears and
skills of our technicians and precision strobe tuners
in an environmentally controlled room in which both
temperature and humidity are kept constant. Precise
tuning of the harmonic overtones, which determine
timbre, results in stable pitch and tone without any
unevenness.
3. Easy Assembly/Disassembly
The instrument is designed to offer easy assembly
and disassembly to provide convenient storing and
transport. The YM-460/460F/410D/46/2400/2400R

pipes to provide the utmost in compact convenience.
