I know the conducting patterns but how do I decide which song needs which pattern? I know it depends on beats and all, but I just can't get the sure shot method of finding the right pattern. can the same song have different patterns? for example one conductor uses the four pattern thrice while the other uses six pattern twice for the same tune.
Two different conductors, one using a pattern to indicate 4/4 time and the other using a pattern to indicate 6/8 time will be leading their musicians to play separate and distinct versions/arrangements of that same song. The conductors pattern is to indicate the rhythm of the music, and the rhythm may change inside the song, but this is led but the conductor and the musicians follow. Failure to adhere to this idea creates mayhem in the orchestra, as you can probably imagine.
