EDUCATIONAL APP
App4L
App4L is the educational app for the 4L Method, dedicated to the study of overtone singing and throat singing techniques.
Through audio examples, ear training exercises, and interactive activities, you can listen to harmonics and sub-harmonics, recognize them, understand their structure, and turn them into melodies.
The new feature indicated by the “👁️” icon activates the microphone and shows exactly which harmonic you are amplifing.

App4L will help you to:
- —develop more attentive listening skills;
- —become familiar with the overtone series;
- —recognize patterns and melodies in Just Intonation;
- —practice selecting overtones through mouth resonance;
- —improve your vocal control and awareness.
App4L is based on a fundamental principle: when the ear recognizes an overtone, the voice can learn to reach it with greater accuracy.
