I am working on a piece for solo jazz piano that includes the following two part writing for the right hand.
It is possible for me to play the sequence beginning on beat 3 without pedaling by holding the lower voice with fingers 1 and 2 while the melody is played with fingers 5-4-3-4. However, does the arranger expect one to sustain the lower voice with pedal to free up the hand to play the melody more smoothly?
There are no pedal markings in this piece, but the book it's included in does include some pedal markings for arpeggiated sections in other pieces.
Generally speaking, is it appropriate to use the pedal (instead of the fingers alone) to sustain a voice in two part writing if you feel it allows you to better phrase the melody? This pattern of a half note voice simultaneously occurring with four sequential eighth notes is fairly common (but often less cumbersome than the example I provided) in the book I'm working through.
