I would have loved it if the Carnival Triumph would have honked back, though we did hear while backing up that this ship has a kind of lame single-note horn. Anyhow, it's a decent recording of my Tyfon collection, and the only time I've blown the A-200, A-300 and 425 together. They blow D#, G# and C respectively, which makes a G# major chord (with the C note an octave below the usual triad position). (less info)
