Metric Modulation Help
I need some help with which symbol to use, as a lot of information online is confusing to me regarding this.
If I want to keep the beats the same tempo as they move from 6/8 to 4/4 (i.e. each of the two beats of 6/8 being same same duration as each of the four beats in 4/4; going from say 70 dotted-crotchets per minute to 70 crotchets per minute) which of the two metric modulation markers should I use? A or B?
A - dotted-crotchet = crotchet
B - crotchet = dotted-crotchet
Thanks in advance!
