Which violinist worked with the American rock band "Seventh Key" who also worked at Tulsa Philharmonic?
David Ragsdale David Lasater Ragsdale, (born April 3, 1958) has been the violinist for Kansas from 1991 to 1997 and from 2006 to the present. He started violin at the age of three. After studies with classical teachers and a stint at the Tulsa Philharmonic, Ragsdale's violinist duties took him out of the largely classical area and into rock and roll.
Minor seventh In music theory, a minor seventh is one of two musical intervals that span seven staff positions. It's "minor" because it's the smaller of the two sevenths, spanning ten semitones. The major seventh spans eleven. For example, the interval from A to G is a minor seventh, as the note G lies ten semitones above A, and there are seven staff positions from A to G. Diminished and augmented sevenths span the same number of staff positions, but consist of a different number of semitones (nine and twelve).
