The term 'high-pitched wind' can be described by two musical instruments: the OBOE (4 letters) and the RECORDER (8 letters). The OBOE is a double-reed woodwind instrument that produces a sound with a distinctively rich, mellow tone. It is commonly used in classical music, but has also been used in jazz, folk, and popular music. The RECORDER is a woodwind instrument that produces a sound with a bright, clear tone. It is often used in early music, but has also been used in modern music. Both instruments produce a high-pitched sound, making them ideal for playing music in the higher registers.
