In music theory , the point of extension is a sign, placed after a figure of note or rest, to extend this figure to a precise and measurable â € "unlike the climax.
- Since about 1750, the period of extension point is always equal to half the previous value - that it is a figure, or another point. Thus we can distinguish: the ordinary point - simply called "point" - the double point and the triple point.
- Before that time, it happens that the point of extension indicates a need to extend the note which is the time needed to fill the time or the measure until the following short note. We then use no double or triple point. This highlights the fact that the musical notation and in particular the pace was not originally designed as a series of notes, but as a series of rhythmic-melodic figures, each comprising one or more notes (see neum ) .
- Do not confuse the point of extension - always placed after a figure - with the point indicating the staccato - it lies above or below a figure of note.
- When the dot follows a figure of note, it must be analyzed as a period cumulatively to the previous value by means of a tie.
Placed after a figure, the point increases the latter half of its duration.
- Alternative values plotted:
- From the above we can deduce that any value pointed worth double the value pointed lower, and half of the value pointed top.
- Relative Value of figures dotting:
- Relative value figures pointed silences:
Placed after a figure, the double point increases it three-quarters of its duration.
- Alternative values double dotted:
- As we have seen, the second point is the first that the first is the original figure, the equivalent of half the value above.
According to the same principle, placed after a figure, the triple point increases this seven-eighths of its value. The triple point is very low.
