The Low Tone Club (Spanish: El club de los graves) is a Colombian comedy-drama television series for children and adolescents produced by TeleColombia for the Walt Disney Company.
Each year, the school's principal, Eduardo Kramer, selects five students who are nicknamed the "High Tones" and become part of the school's prestigious teen band.
Molina, on the other hand, is in charge of the so-called "Low Tones," a group of students whose talents do not meet the school's standards.
The headstrong teacher and the "Low Tones" embark on a musical journey in which the teacher's unconventional methods help heal wounds and inspire each of them to express their unique talents.
Along the way, the students learn more about Mr. Molina and encounter their teacher's mysterious past, which he always tries to hide.
