The pattern of black keys on the keyboard is described as what?

• A. In alternating groups of two and three
• B. In a continuous row of five
• C. In random groups
• D. In groups of four

Answer: (A)

The pattern of black keys is described as alternating groups of two and three. This happens because within each octave there are five black keys spread around the white keys in a repeating way: the first two black keys sit between C–D and D–E, forming a pair, then the next three sit between F–G, G–A, and A–B, forming a trio. This grouping repeats from one C up to the next C, so the keyboard shows consecutive two-key then three-key clusters across its length. The arrangement aligns with the gaps where there are no black keys between E–F and B–C, so you never get a continuous row of five black keys. This pattern is a handy landmark for navigating the keyboard and finding notes quickly.
