Klang-Spektrum
Music theory step by step: reading notes, rhythm and intervals – building on one another, with short units and clear progression. For school, music lessons and home.
The fundamentals, cleanly built up
Klang-Spektrum guides you through the most important topics of music theory – clearly, in small steps and with repetition, so that it really sticks.
Reading notes
From the staff through treble and bass clefs to the note names – the written language of music from the ground up, with mnemonics for quick recognition.
Rhythm
Note values, rests, time signatures and tempo: listen, count out loud and tap along until the pulse sits securely.
Intervals
Recognise and name the distances between notes – with listening examples and familiar anchor songs.
Solfège & colours
Do-Re-Mi and fixed sound colours make pitches tangible and easier to remember – especially for inner hearing.
Glossary
Look up the most important technical terms briefly and clearly – available in four languages.
Listening & applying
Ear-training exercises connect theory with real sound – because knowledge truly comes alive only through listening.
How you learn with Klang-Spektrum
Music theory rarely fails because of ability, but often because too much comes at once. Klang-Spektrum therefore relies on a few proven principles from learning research – the same ones that work in good music teaching:
- Small units: Each topic is broken down into manageable steps. Practising just one concept at a time means you retain it more reliably.
- Building on each other: First the note names, then rhythm, then the distances – each new topic rests on the previous one. That way no gaps appear.
- Repetition with spacing: What you have learned keeps coming back, rather than being ticked off once. This distributed practice (spaced repetition) anchors knowledge for the long term.
- Hear, see, do: A note is seen, heard and reproduced. Addressing several senses at once consolidates learning markedly better than reading alone.
Short, regular sessions – around ten minutes a day – achieve more than rare long ones. That is exactly what the app is designed for: a little further every day rather than a lot at once.
Solfège and sound colours – why they help
Solfège: Do, Re, Mi
Solmization (solfège) gives each degree of a scale a syllable: Do, Re, Mi, Fa, Sol, La, Ti. In the common “movable do” form, Do is always the tonic – whatever key you sing in. This way you learn the relationships between notes, not just individual names. “Ti”, for instance, audibly leans back up to “Do”. Anyone who can sing melodies in these syllables develops “inner hearing” and pitches notes more securely.
Fixed sound colours (the Boomwhacker principle)
In the colour-coded approach every note is given a fixed colour – the same principle as the well-known Boomwhacker chime tubes, where C is red, for example, and the notes follow a rainbow-like order. For beginners this is a bridge: before abstract notation is firmly in place, melodies can be recognised, played along with and memorised through colour. Colour speaks to the eye, sound to the ear – together they make pitch graspable.
Made for the classroom
Age-appropriate from 10 years
Klang-Spektrum is designed for 10- to 17-year-olds and can be used without prior knowledge – in music lessons, in a club or for practice at home. Parents and teachers will find how to use the app in everyday situations in the School & Family section.
Ideas for using it
- As a starter: Go through a short topic together at the beginning of the lesson and then apply it on the instrument.
- For differentiation: Faster learners practise on independently while others repeat a topic at their own pace.
- As homework: Spend ten minutes a day deepening one topic – that fits well between lessons.
- For reference: Clarify unclear terms directly in the multilingual glossary, also for learners with another first language.
FAQ
What age is the app intended for?
Klang-Spektrum is aimed at young people aged roughly 10 to 17. For younger children (from 6), the sister app Klang-Regenbogen is the better, playful introduction.
Do you need prior knowledge or an instrument?
No. The topics start from scratch and build on each other. An instrument is not necessary, but helps you apply what you have learned right away.
Which topics does the app cover?
The focus is on reading notes, rhythm and intervals, complemented by solfège, colour-coded pitches, ear-training exercises and a multilingual glossary.
Can I also read up on the topics without the app?
Yes. All topics are available as free learning pages in the browser – ideal for preparing and reviewing, or for revising without a device.
