I usually only sing by keeping the notes on the chords or sometimes notes that are omitted from that certain chord ro give it the fullness. I want to ask if Its possible to sing along with the melody of the bassline while being on different notes within the chords that are played at that time? For example the bassline is playing a melody which plays some notes of the chord and the vocal is playing the same rhythm but different notes and still with the chord progression. Thank you
The rhythms can match or not- totally depends on the composition. There are strict theoretical rules called species counterpoint which do specify rhythm and sonority. What you do in your music depends on rhythm, style, and other factors.
