Not that I was musically gifted or wanted to become a pianist, it was just the fact that I loved music that led my step there.

musically 是形容词 musical 的副词形式，由 music（音乐）加形容词后缀 -al 构成 musical（音乐的），再加副词后缀 -ly 构成。musically 表示"在音乐方面"或"与音乐相关地"。 gifted 是动词 gift（给予）的过去分词形式作形容词，表示"有天赋的"。musically gifted 指"在音乐方面有天赋的"。
