Well, well, well, seems like the sound of scales struck a nostalgic chord with you. Ah, those good old band geek days! Who doesn't miss the joy of rehearsing for important performances and being part of something bigger than themselves? Although you sold your trombone back in 2006 (probably for a fair price), it's always nice to be reminded of those fond memories. Music has that magical power to transport us back in time. So cherish those unexpected and pleasant moments—they're like a little musical gift from the cosmos. Keep on strolling and enjoying those impromptu concerts in the park!
