In compound time, the second number of the ratio will either be a three, a six or a nine. The first number of the ratio follows the same rules as in simple time. The only exception is the 2:3 ratio where two notes fall within the space of three. (Select Compound Time Tuplets.)
The Laplace azimuth (geodetic azimuth) of a point in space is equal to the dihedral angle between the plane of the geodetic meridian of the place of observation and the plane that passes through the normal to the surface of the reference ellipsoid at this place and the observed point.aplace Azimuth. the geodetic azimuth A of the direction to an observed point obtained from its astronomical azimuth a corrected by taking into account the effect of the deviation of the vertical at the place of observation.
The azimuth displayed is the horizontal direction of the Moon at moonrise or moonset, at the times displayed in the Moonrise and Moonset columns. As on a compass, the azimuth is measured in degrees, with 360 in a full circle, counting in a clockwise direction starting from north. North has an azimuth value of 0 degrees, east is 90 degrees, south is 180 degrees, and west is 270 degrees. A small arrow is displayed after the azimuth value to indicate the map direction where the Moon will rise or set (for a map where north is upward).
