Ties connect one note value to another. It is especially common over a bar line. Sometimes two notes may be tied within the same measure.

If the note being tied over a bar line has an accidental, the accidental is also carried over.

The curve of the tie may be up or down depending on the stem directions of the note on the musical staff. For the stem going downward, the tie is curved up, starting above the note head, from one note to the other. Likewise, for the stems going upward, the tie is curved downwards, starting below the note head, from one note to the other.

One or more of any note within a chord may be tied to another. The tie is curved upward for the top note of the chord and the tie is curved downward for the bottom note of the chord. For the notes in between the chord, the ties are evenly alternated between the upper and lower curved ties.
