It seems like you're referring to a music excerpt, but I'm unable to play audio or provide real-time audio analysis. However, if you're asking how to determine if a piece of music is in a major or minor key, you can consider the following factors:
- Harmony: Major keys often have a bright and happy sound, while minor keys tend to sound darker or more somber.
- Melody: Listen for the use of certain notes typical to each scale. Major scales have a pattern of whole and half steps (W-W-H-W-W-W-H), and minor scales have a different pattern (W-H-W-W-H-W-W).
- Tonic Chord: The tonic chord (the first chord in a key) will typically sound final and resolved in its respective major or minor context.
If you have specific details about the music or can describe what you hear, I can help with further analysis!
