Final answer:
The kettledrum is an important percussion instrument in an orchestra but not necessarily the most important as each instrument's role can vary with the music. As part of the orchestra, instruments are tuned together, with woodwinds often playing high frequency notes and strings playing a variety of frequencies.
Step-by-step explanation:
The statement that the kettledrum is the most important percussion instrument of the symphony orchestra can be considered false because while it is indeed a crucial instrument, the importance of an instrument can vary depending on the piece of music and the role each instrument plays within it. In an orchestra, different instruments including strings, woodwinds, brass, and percussion come together to contribute to the overall sound. The kettledrum, or timpani, adds depth and drama to the music, but it is not inherently more important than other percussion instruments such as the snare drum, cymbals, or xylophone.
All members of an orchestra typically begin tuning their instruments at the same time before a performance. This creates a harmonious starting point for the music that will follow. While woodwind instruments might play high frequency notes, other instruments such as those from the string section may play lower frequency notes, creating a rich tapestry of sound.
