When did the second phase of electrical instruments begin?

• A. In the 1930s
• B. After WWI
• C. In the 1950s
• D. At the end of WWII

Answer: (D)

The main idea here is how electronic instruments evolved in stages, with the second stage kicking off when postwar technology opened the way for practical, widely used electronic sound tools. After World War II, advances in electronics—more reliable tubes and the groundwork for transistors, along with the rise of tape recording and new studio infrastructure—made electronic sound generation and manipulation feasible on a larger scale. This shift from wartime research to peacetime music technology allowed electronic instruments to move from experimental prototypes to real performers and composers’ tools, marking the start of a new, distinct phase. Earlier in the 1930s you had important inventions like theremins and Ondes Martenot, but they were largely isolated experiments and not yet part of a broad, sustained movement. Starting points after WWI are too early, and while the 1950s reflect the growth of the second phase, the transition edge is best placed at the end of World War II.
