Note the homophone trap: the musical instrument 扬琴 (yángqín, hammered dulcimer) has the same pinyin. If you hear 'yangqin' in context of a person it's the name 杨琴; in context of music it's the instrument 扬琴.
memory
琴 = two 王 (king / jade) side by side over 今 — a classic mnemonic: 'two jades sounding together today' = the ancient seven-stringed zither.
