Benefits
Two primary benefits are claimed by the inventors and enthusiasts of isomorphic keyboards:
- Ease of teaching, learning, and playing
- isomorphic keyboards' invariance facilitates music education and performance. This claim has not been rigorously tested, so its validity has been neither proven or disproven.
- Microtonality
- isomorphic keyboards' provision of more than the usual 12 note-controlling elements per octave facilitate the performance of music that requires more than 12 notes per octave.
A third potential benefit of isomorphic keyboards, dynamic tonality, has recently been demonstrated, but its utility is not yet been proven. Using a continuous controller, a performer can vary the tuning of all notes in real time, while retaining invariant fingering on an isomorphic keyboard. Dynamic Tonality has the potential to enable new real-time tonal effects such as polyphonic tuning bends, new chord progressions, and temperament modulations, but the musical utility of these new effects has not yet been demonstrated.

Famous quotes containing the word benefits:
“It is with benefits as with injuries in this respect, that we do not so much weigh the accidental good or evil they do us, as that which they were designed to do us.—That is, we consider no part of them so much as their intention.”
—Laurence Sterne (1713–1768)
“In America the young are always ready to give to those who are older than themselves the full benefits of their inexperience.”
—Oscar Wilde (1854–1900)
“Unfortunately, we cannot rely solely on employers seeing that it is in their self-interest to change the workplace. Since the benefits of family-friendly policies are long-term, they may not be immediately visible or quantifiable; companies tend to look for success in the bottom line. On a deeper level, we are asking those in power to change the rules by which they themselves succeeded and with which they identify.”
—Anne C. Weisberg (20th century)
