Final answer:
The statement that four popular instruments include piano, strings, guitar, and saxophone is true, as these instrument classifications are accepted in the study of music and used across various music genres.
Step-by-step explanation:
True or false: Four popular instruments include piano, strings, guitar, and saxophone. To answer this question, we can reference a common classification system used in the study of music. Instruments are typically classified based on how their sound is produced.
For example, the guitar would be classified as a chordophone, which is a type of stringed instrument. Other classifications include aerophones (wind instruments), membranophones (instruments with a membrane, such as drums), and idiophones (self-sounding instruments). Some examples representing different types of instruments are flutes for aerophones, violins for chordophones, drums for membranophones, and so on.
In the context of a western music class, instruments like the piano are considered stringed instruments even though they are often categorized separately as keyboards, guitars (acoustic or electric) are chordophones, and the saxophone is a woodwind, fitting within the wider category of aerophones.
Therefore, the statement that four popular instruments include piano, strings, guitar, and saxophone is true, as they are all well-recognized and commonly used within various genres of music.
