Let Me Tell You a Real Story
Saturday, 4:00 PM. We were on stage, doing the soundcheck for a major guitar festival. I had been hired as a session musician for the band of the main star—a world-class guitarist.
Right on time, he arrived, ready to rehearse with the four winners of a contest who would have the once-in-a-lifetime chance to jam with him later that night. Then, without hesitation, he said:
"We’re changing the song for the jam. New key, new chord changes."
For us, the band, it was just another day at work—we nodded, understood, and got ready. But then, one of the contest winners froze. His face went pale.
"I don’t know anything about notes," he muttered, his voice barely audible.
Silence.
A long, painful silence.
Everyone looked at the main guitarist, then at the event organizer. The tension in the room was suffocating. Finally, the organizer sighed and said:
"We’re out of time. The show starts at 5:30 PM. Sorry—you’re not playing."
And just like that, it was over.
The concert was sold out. 3,000 people filled the venue. The night was unforgettable for everyone—except for one musician who was supposed to be on that stage.
We never know when opportunity will knock. Will you be ready when it does?
Tired of Watching Videos but Not Progressing?
❌ Overloaded with endless music theory and harmony tutorials but still struggling to play your favorite songs or create yours?
❌ Collecting PDFs, books, and YouTube videos but feeling stuck?
❌ Want real feedback instead of guessing what you’re doing wrong?
You’re not alone. Pre-recorded courses are great for learning specific skills or solving specific questions, but they don’t offer real-time feedback. Those work for musicians that already have deep knowledge about the subject.
Without proper guidance in real time, many people can struggle to correct their mistakes and progress effectively.
In Music Theory, this is also a major issue
👉 That’s where this LIVE, personalized coaching makes all the difference 👈
What You'll Learn in this course:
🎵 How to instantly find the key of any song, so you can confidently make arrangements, improvise with your instrument, create vocal harmonies, for example.
🎼 How to communicate with other musicians in real time, making rehearsals, recording sessions, and concerts effortless.
📖 How to read and write sheet music, accurate tabs, and lead sheets, so you never feel lost when working in your music and with other musicians.
… Among many many other things.
Who Is This For?
✅ Musicians tired of guessing because they don’t truly understand what they’re playing.
✅ Producers frustrated by trial and error, spending hours on chord progressions that never sound original.
✅ Singers and instrumentalists who want to bring lead sheets to life without feeling lost.
✅ Songwriters who want to break free from the same progressions and discover new creative possibilities.
✅ Musicians who freeze at a jam session when someone says, “Take a solo—16 bars in G minor.”
✅ Anyone serious about mastering music and unlocking their full potential.
Meet Your Teacher
Hi, I’m Mauricio!
If my name sounds like someone who should be hosting a cooking show, I assure you—my real specialty is cooking up music.
I’m a musician, bass player, composer, and educator originally from Chile, now based in Berlin. For over 20 years, I’ve been making music, teaching, and helping artists bring their ideas to life.
I’ve played on big festival stages, toured internationally, recorded albums, and even performed with symphonic orchestras (yes, bassists can do that too). Oh, and I won a Pulsar Award—which is like the Chilean Grammys but with better food.
More importantly, I know what it’s like when people feel lost in music theory. That’s why I teach in a way that makes things click, focusing on real-world situations, creativity, and fun. Whether you want to write, arrange, or just finally understand what’s going on in your favorite songs, I’ve got you.
Let’s make music make sense—together! 🚀🎶
Course Program:
This program follows a clear, structured path that takes you from confusion to confidently creating your own arrangements and working like a pro. It’s the ultimate way to master music theory seamlessly.
I break down every concept into the simplest terms, ensuring you truly understand—always with real-time feedback.
You will see results immediately in your music, from the first meeting:
-
Staff, clefs and music notes
The Concept of tone and semitone
The Major scale
By the end of this lesson, you’ll grasp the foundational elements of music and how they come together to form a scale, and how to use that in your music.
-
The circle of fifths & fourths
Applying key signatures to build major scales.
By the end of this lesson, you will understand how to recognize and use every major scale in your music.
-
Distance, type, and calculations
How to recognize and use intervals musically
Intervals are essential for understanding chords, keys, and the foundation of music organization - yet many find them confusing. By the end of this lesson, you'll have a clear grasp of intervals and how they function in music.
-
How to build triads & harmonize a major key
Reharmonization basics & transposition
Analyzing your favorite chord progressions in a major key
By the end of this lesson, you'll be able to build chords effortlessly from your head—no charts or templates needed. You'll also understand why some chords work together while others don’t. Your days of guessing chords are over.
-
Rhythm notation & time signatures
Tied & dotted notes
Conducting music & rhythmic grouping (until subdivisions of 8)
By the end of this lesson, you'll be able to understand how notes are structured in bars and staffs, read them, and confidently count beats when playing or listening to music.
-
Building tetrads
Natural minor scale and key
Harmonic minor scale and key
How to work in a minor key
Introduction to harmonic analysis
We started with major keys because minor keys are built from them. By the end of this lesson, you'll be able to work in both, understanding the structure behind most of the music you hear and play.
-
Three types of music reading: rhythm, naming notes, with pitch
Subdivision of 16th
Triplets
Rhythm Pyramid
By the end of this lesson, you'll be able to read any music score—giving you the foundation to master music reading as far as you choose.
-
Melodic minor scale and key
Cadences
Inversions
Chord symbols, with tensions
With a full understanding of the tonal system, it's time to apply it. By the end of this lesson, you'll know how to use its elements creatively in your music.
-
Different rhythm exercises
How ear training works
Music dictation exercises
How to transcribe music by ear on paper using your instrument / voice
After this lesson, you'll have the tools to develop your ear independently, making you faster and more confident when working in real time with music and musicians. Now, you take control!
-
Substitute and secondary dominants
Modes
Modulation / key changes
Modes are much more than playing a C major scale from D to D (dorian), or from G to G (mixolydian); or memorizing countless fretboard diagrams—they are independent tonalities with their own identity, key signature, cadences, and uses. Many free tutorials leave you more confused than before, missing the main point: how to use them confidently in your music.
After this lesson, you'll not only be an authority in working with modes, but also gain the foundation to understand key changes with confidence.
-
Modal interchange
Fundamental of Blues
Harmonic analysis of any song
Harmony analysis of your own and / or favorite songs
By the end of this lesson, you'll truly understand how music works—allowing you to analyze any song, read any sheet, and know exactly what to do.
No more guessing, no more fretboard diagrams, no more “magic formulas”, no more confusion—just clarity and confidence. You’re now a different musician, ready to apply your knowledge and communicate with others like a pro.
Congratulations, you’ve earned it!
-
Harmonic continuity
Introduction to composition: Vertical and horizontal análisis in melodic lines
Final assignment: Create basic composition or arrangement, write it in a score and make an harmonic and melodic analysis
But wait, there is more. Now you got the very basic fundamentals of music composition, so you can make your final assignment.

What Students Say:
⭐ ⭐ ⭐ ⭐ ⭐
🗣️ “I took the music theory course with Mauricio, and I am completely grateful for it. He made me understand in an easy and entertaining way how music works. And I use this knowledge not only in my instrument, but also in the arrangements and production of my own songs. Absolutely recommended.”
– Juliette Pabst, New York, USA
⭐ ⭐ ⭐ ⭐ ⭐
🗣️ “I started playing bass in 2008 but, as a self-taught player, I never developed real knowledge of music theory and I felt it was hindering my progress.
In 2022 I started having lessons with Mauricio, with the intent of learning how music works and developing my technical skills.
I now feel like I understand music at a much deeper level and in about one year of lessons, I went from knowing very little about music theory to being able to arrange songs into solo pieces for the 6-string bass, which I've since played live.
Mauricio is a very experienced and committed teacher, with a modern and pragmatic teaching style that has made me a much better musician and who I would highly recommend”
