Duration of the notes
I told you when to strike a key, but I did not tell you, when to release it. In principle a key is released at the same time that a new key is played by the same hand. The first (black) key is released at the moment that the second (white) note must be played. So the duration of the first note is one count. The next white note sounds for one count too, because a new white note must be played on count 3.
Let's look, for a moment, only at the right hand notes. Then you will see, that it lasts 4 counts before the next notes appear. But above the bar line of the second bar, so two counts after the last right hand note was played, you can see a little sign, looking like a 'v'. That sign is called a 'stop sign' or a 'rest' in Klavar terminology. This sign indicates, that the note above this sign has to stop at that moment. So the key must be released, without striking another key with the same hand. This is an exception to the rule I stated before. And another is coming.
Now let's look at the left hand. This hand has nothing to do during the first three counts of the first bar. But on count 4 of it a note must be played. One count later, so on count 1 of bar 2, this note is released, because a chord must be played. On count 2 of bar 2 you will see another sign, that has not been discussed. In this case it's a dot underneath the white note of the previous chord. At the same level, so at the same time, you will see a black note, that must be played again. According to the rule the white key should be released, but the meaning of the dot is to indicate, that the note above it must continue sounding, so the key must not be released. The dot is called a 'continuation dot'. And here we have our second exception to the rule. With the knowledge now available we can complete the rule as follows: a note is released as a new note must be played by the same hand or when a rest for that note is found, except for the case a continuation dot prevents that. On the next count line you will see two rests, indicating that the notes of the chord must stop. From there on the left hand has nothing to do anymore.
Let's complete the example. At the moment, that the left hand releases the notes of the chord, so on count 3 of bar 2, the right hand plays a chord of two white notes and that during 2 counts, as you can see from the two rests at the bar line of bar 3 (that has been drawn for only a very small part).
The example doesn't show the possibility to start or stop notes between two count lines. Notes with a duration, that not equals a count, are very often used in real music. In Klavar these notes or rests are placed between the count lines exactly on the position on which they must start or stop, considering the stave to be a linear time ruler. |
