In music notation, the symbols typically represent different note values as follows:
-
Ta Di: This usually refers to a rhythmic pattern in some educational methods, commonly found in Eastern music education. However, if the context is Western music, "ta" often represents a quarter note (1 beat) and "di" might represent an eighth note (0.5 beats).
-
Triplets: A triplet divides a beat into three equal parts. The note value of each note in a triplet depends on the context (which note value is being divided). For example, in a quarter-note triplet, each note is one-third of a quarter note (which is typically 1 beat), so each note would last for about 0.33 beats.
-
Quarters: A quarter note is generally represented by a filled-in oval note head with a stem and typically equals 1 beat in 4/4 time signature.
-
Eighths: An eighth note is represented by a filled-in oval note head with a stem and an additional flag or by connecting to another eighth note with a beam. Each eighth note is half a beat in 4/4 time (0.5 beats).
-
Sixteenths: A sixteenth note is similar to the eighth note but has two flags or beams. Each sixteenth note is a quarter of a beat, so in 4/4 time, four sixteenth notes would equal one beat.
In summary:
- Ta: Quarter (1 beat)
- Di: Eighth (0.5 beats)
- Triplets: Varies based on the note value divided, typically 1/3 of the base note value.
- Quarters: 1 beat
- Eights: 0.5 beats
- Sixteenths: 0.25 beats
