What is the transposition for an Alto flute?

The Alto flute is a musical instrument that is transposed when compared to the concert pitch. Specifically, when playing the Alto flute, the music is written in the key of G, and the sound produced is a perfect fourth lower than what is written. This means that when a musician reads and plays a written note on the Alto flute, it sounds a perfect fourth below that note.

For instance, if a written C on the Alto flute is played, it will actually sound like a G. It’s essential for musicians and composers to understand this transposition for accurate scoring and performance in ensemble settings.

The other options suggest different transpositions that do not accurately represent the Alto flute's characteristics. Understanding the proper transposition for instruments like the Alto flute is crucial for effective collaboration in any musical context.
