In this lesson, we explored the string section of the orchestra, which includes instruments like the violin, viola, cello, and double bass. We learned about the materials these instruments are made from and practiced identifying them both visually and by their sound. The violins are divided into first and second, with each group playing complementary parts. The double bass is the largest instrument in the string section, producing the lowest pitches, while the violin produces the highest sounds, highlighting the balance necessary in the orchestra.
