Basics
Another way to create a more specific note values is to use a TIE.
Using a tie between two notes combine there durations.
You might be wondering - “why would I use a tie when I could just write a half note?”
Say we have two bars of 3/4 (like below), and we want who ever is reading the music to play 3 half notes consecutively.
This makes absolutely no sense.
One measure has one quarter note too much and the other measure is missing a quarter note.
Ties allow us to represent an unbroken note across one or several measures.
The correct way to accomplish this is illustrated bellow.
Other uses for ties can be found in Notation Skills section Barring.
