¿Cuál es la diferencia entre 3 8 y 6 8 minutos?

It looks like you shared a great summary and reference from Hoffman Academy about the differences between 6/8 and 3/8 time signatures!

Even though both time signatures have an 8 on the bottom (meaning the eighth note gets one beat's worth of subdivision), they feel and count very differently:

• 6/8 Time (Compound Duple): Has 2 main beats per measure, where each beat is divided into triplets (dotted quarter note pulse: ONE−la−li,TWO−la−liONE-la-li, TWO-la-liONE−la−li,TWO−la−li).

• 3/8 Time (Simple Triple): Has 3 main beats per measure, where each beat is a single eighth note (1,2,31, 2, 31,2,3).

Did you have a specific question about these time signatures, or were you looking for help counting a particular piece of music?
