Legato means to play connected, and the key element to achieving this is minimizing any gap between notes.

When playing two notes on the same string, synchronize your hands to ensure a smooth connection without anticipating the next note too early.

Playing notes on different strings presents a challenge in maintaining a consistent tone due to the different timbres of the strings.

To connect notes played on different strings, allow a brief overlap where both notes ring together, helping the ear perceive them as one continuous sound. Legato means to play connected, and I advise developing legato fingerings when playing on the same string or across strings, as well as using portamentos.

When playing legato on one string, ensure the gap between both notes is as tiny as possible.

For notes across two strings, try to make them overlap to achieve a smoother legato sound.

Portamentos imitate how we would sing between two intervals, especially when there is a large leap, by subtly filling in the distance between notes.

To achieve a clean portamento, avoid pressing too strongly or too lightly while shifting; find a balance in pressure to connect the notes elegantly.

When applying legato techniques to a piece, start by playing the notes without overlapping, then gradually introduce overlapping and portamento for a smoother sound.

Using vibrato can enhance the illusion of sustain in your playing, contributing to a more connected legato sound.
