Dotted note note is used less frequently than the dotted note. Typically, as in the example to the right, it is followed by a note whose duration is one-quarter the length of the basic note value, completing the next higher note value. Before the mid 18th century, double dots were not used. Until then, in some circumstances, single dots could mean double dots. In a French overture (and sometimes other Baroque music), notes written as dotted notes are often interpreted to mean double-dotted notes, and the following note is commensurately shortened; see Historically informed performance. A triple-dotted note is a note with
Pulses per quarter note Pulses per quarter note PPQN (Pulses Per Quarter Note, also known as PPQ, Pulses Per Quarter and TPQN, Ticks Per Quarter Note) is the smallest unit of time used for sequencing note and automation events, both by step sequencers and in the MIDI standard. Most MIDI sequencers allow the number of PPQ to be varied for more or less temporal resolution depending on the needs of the performer. If there are too few PPQ any performance recorded into the MIDI sequencer may sound artificial (being quantised by the Pulse rate) or lose subtle variations in timing that gives music a
