How to play a note with a connecting symbol on the skipping symbol of the piano score? The following figure

This is called staccato, which is a kind of staccato. There are three commonly used staccato:

Special effects: there is a small black triangle above the note, upside down, and the duration of the note itself is1/4;

Jump: there is a point above the note, and the duration of 1/2 of the note itself is played;

Staccato: There are both lines and jumping points above the notes, which is your picture, and the duration of playing the notes themselves is 3/4.

Playing three jumps here requires consistency, and you can add a sustain pedal when playing.

Namely that rightmost one of the three pedal under the piano.

When playing in this way, it is still played in a skipping way, and the three notes are coherent, which is in line with the expression of the score.

Two identical notes of extended data are connected by a line, which is called sustain line.

Two or more different notes are connected by a line. This line is called a hyphen.

The function of sustain line is to prolong the duration of notes. The second sound is a continuation of the first sound.

The purpose of ligatures is to make two or more different notes play smoothly. Just like when we speak, we should make sentences instead of jumping out word by word. Therefore, connecting lines are also called smooth lines.

If it is a piano, play the sustain line. You only need to play the total duration of two notes.

When playing Legato, the first note should be raised and the other notes should be played smoothly. When the last sound is played.

Raise your wrist when you're done.
