What is the sequence of the order of double reed instruments?

The sequence of double reed instruments reflects their common classifications and relationships within the woodwind family. The correct answer highlights the proper order of these instruments based on their sizes and tonal registers.

Starting with the oboe, which is typically the smallest and has a higher pitch, followed by the bassoon, which is larger and plays in a lower register. The double bassoon, even larger than the bassoon, extends the range even lower. This progression from the higher-pitched oboe to the lowest-pitched double bassoon demonstrates a clear ascending order in terms of size and descending order in terms of pitch.

In contrast, other choices feature combinations of instruments that do not follow this logical sequence. For instance, including the clarinet—which is a single reed instrument—in a sequence of double reeds disrupts the classification. Similarly, placing instruments like the cor anglais or varying the order disrupts the understood hierarchy based on tonal characteristics and physical size. Thus, the correct sequence captures the essential characteristics of double reed instruments in a coherent format.
