Semi-related to a question from the other day, but when you think of train horns in movies, which of the following comes to mind? K5LA, RS3L, "Canadian-tuned K3L", M5, "Old Cast P5"
none of those names come to mind because i am not familiar enough with the names. but when listening to all of them, it is very clear that the ones that play a major6 or major7 chord are going to be best for jovial, jolly horns. where as some of the others were much more frightening, good for other contexts
