CF4

The six foot three length of the CF4 is small enough for a recital hall or teaching studio, but it has a surprisingly big sound. 

Designed with the concept of “Beauty and Power”

 Power describes the incredible tonal presence. Not only when played fortissimo, but even soft delicate passages carry throughout the hall. The bass is amazing, and all registers can project over a full symphony orchestra regardless of a venue’s size.

• Ribs & Soundboard– only the most carefully selected European spruce is used for the soundboard. A new method for attaching the ribs to the soundboard helps free it from stress, adding rich overtones to the sound for a wide range of expressive tonal colors.
• Metal Frame – individually hand molded and sand cast to enhance the strength and stability of the pianos. This contributes to the outstanding tonal character and sustain of the series. 
• The hammers have a big affect on the tonal clarity and character, and also help determine how the sound projects and sustains. Yamaha uses the best possible materials and treatments for optimum performance despite possible changes in temperature and humidity.
• All aspects of the piano wire have been researched―from the wave patterns of various harmonics to the way it reacts when struck by the hammers. Both materials and manufacturing methods are very important, and Yamaha's bass strings are hand wound by skilled craftspeople.
