Try the following exercises continuing to rest p on the 6th string for support.
Practice "strongly", only use small finger movements i.e. at no time should the fingers be more than p" (13mm) from their respective strings.
These exercises introduce the quarter note (or crotchet) 3, which is worth one count. In ^ time (Ex. 1-5) there are three quarter note beats per bar and in * time (Ex. 6) there are four quarter note beats per bar.
The following exercise in * time, involves two and three open string notes played together. Use the same procedure as outlined above; be sure to keep both (or all) fingers together at the tips and make the notes sound as one.
