'Bass' is a low musical register or a freshwater fish; 'base' is a foundation, headquarters, or the adjective meaning low or dishonorable.
Noun/adjective. The lowest musical register. A bass guitar or bass singer. A fish (freshwater bass, sea bass). Note: 'bass' (music) is pronounced /beɪs/; 'bass' (fish) is /bæs/ — two different words, same spelling.
The bass guitar provides the rhythmic and harmonic foundation of the song.
Turn up the bass — I can barely feel the rhythm from here.
He has a deep bass voice that resonates through any room he speaks in.
Noun/adjective/verb. The foundation or lowest part of something. A military or operations headquarters. A starting point. Adjective: dishonourable or mean. Verb: to found or ground something on.

Common mistake
"The song needs more base" when meaning the low musical frequencies (correct: bass). Or "A bass salary" when meaning the starting pay (correct: base salary). Very common in music writing.
Trick to remember it
'Bass' has SS like 'pressure' and 'mass' — deep, heavy sounds. 'Base' has ASE like 'case', 'place', 'space' — foundational, positional concepts.
Quick rule
Is it the low musical register or the fish? 'Bass'. Is it the foundation, headquarters, or the adjective meaning low/dishonourable? 'Base'.
Did you know?
Leo Fender invented the electric bass (Precision Bass) in 1951 — making the bass line portable and amplified for the first time. Before this, jazz and blues bands used an upright double bass. The electric bass guitar transformed popular music. Trivia: 'bass' (music) and 'bass' (fish) are spelled identically but pronounced differently — /beɪs/ for music, /bæs/ for the fish. They are etymologically unrelated: the fish 'bass' comes from Old English 'baers', while the musical 'bass' comes from Italian 'basso' (low).
