Is the upper door panel on the piano put together in two pieces

The upper door panel of the piano is assembled in two pieces.

The current bonding technology does not affect the strength of the material in any way, but also increases the strength and prevents insects. In addition, the surface of the keys is also bonded.

Expanded Information:

1: The piano soundboard system is one of the most important acoustic components of the piano sound (also known as a Yardstick, a *** sounding board, and a string tensioning system). The soundboard system is one of the most important acoustic components of the piano's sound source (also known as the yardstick,*** sounding board, string tensioning system). Its role is to vibrate the strings issued by the sound waves through the *** vibration principle to increase the volume and conductivity, improve the sound quality and other roles.

2: soundboard system includes: soundboard (also known as *** sounding board, ringing board), ribbed wood (gear), string code (including long and short code that is the middle and high and low string code), soundboard frame (including oblique frame) and other parts.

3: The best material for the traditional piano soundboard is high-quality coniferous wood, such as fish scale spruce, the best species is the European spruce, especially produced in the Bavarian region between Germany and Austria and the mountains of the northern Apennine Peninsula of the spruce is the best quality, but the price is very high. Early Chinese pianos used spruce (also known as one of the white pines) and red pine produced in the northeast of China's Xiaoxinganling and Changbai Mountains. Due to environmental reasons, domestic logging is basically prohibited, and now domestic soundboards are mostly made of spruce from the Russian Far East, or imported from North America and other places with similar species of wood. Ribbed wood (gear) should also be used and the soundboard of the same species of wood production.
