recently started playing in a new community band and the lead trumpet player was a high school band director for a couple of years. He is directing one piece at next weeks concert and he stated that when an eigth note is tied to any other note [such as a quarter or half note] the composer does not want the tied note played the eigth that is tied on but that to hold the note the full value before the eigth. the eigth note is actually a rest. This was confusing to me as I was always used to playing the notes to their value and the resting to the value of the rest that was written. He was very emphatic that this was how composers get someone to play a whole-half or quarter note to their correct value. I guess at 60 yrs. of age I learn something new all the time. To the good musicians out there have I been wrong all these years or is he full of beans?
