I noticed this weekend at the Nationals the adjudicators talking about intonation over and above basic tuning - I got wondering, How many bandsmen really know what intonation is? and how do you explain it to others? My understanding is, intonation is how the notes in a chord sit together to make that chord in tune. For example - three horns playing g's - tuning. three horns playing G,B,D - intonation. . . Am I close?
