Base & Bass

Base – the lowest surface of an object, upon which it rests. Similarly, a surface upon which another object rests, even metaphorically as a "base of operations." Also, chemically, the opposite of an acid.
Bass – the lowest/deepest range of musical notes, or the voice/instrument that produces them.
