What is the name of Sigma Alpha Iota's fraternity journal?

The fraternity journal of Sigma Alpha Iota is known as "Pan Pipes." This publication serves as a platform for sharing news, articles, and resources related to the activities and interests of SAI members. It helps foster communication among members and provides insights into the organization’s events, initiatives, and the broader music community.

The other options, while they may sound like plausible titles for a music-related publication, are not associated with Sigma Alpha Iota. "Tempo!" is often tied to musical terminology rather than specifically to SAI, "Music Notes" has a generic appeal to music lovers but lacks specific ties to the fraternity, and "Sound Waves" could refer to a broad range of sound and music-related topics but is not the official name of SAI's journal. Thus, "Pan Pipes" is distinctively recognized as the correct journal for Sigma Alpha Iota.
