In TwinNote intervals are visually distinct which makes it easy to differentiate between them. This is the effect of TwinNote’s 6-6 pitch pattern found in its two types of note heads. If an interval spans an even number of semitones the triangle notes always point in the same direction. If it spans an odd number of semitones the triangle notes always point in different directions.
For example, you can clearly see the difference between major seconds and minor seconds (shown above), which is not possible in traditional music notation. When compared with intervals in traditional music notation, TwinNote is more clear, consistent, and direct.
Intervals are some of the most basic building blocks of music. Being able to clearly and consistently see the differences between them leads to a better awareness and understanding of music and common musical patterns.
Improvising and playing by ear are skills that are largely done through interval relationships between notes. Yet in traditional notation these relationships between notes are obscured. How might one’s ability to play by ear and improvise improve through using a better music notation system?
Below is a comprehensive illustration of all the common intervals. The number of semitones spanned by each interval is given in parentheses.
