We are going to reveal THE secret of the pros
It is called : Number System


The Number System

Have you ever heard about Number System? (also known as Nashville number system)

Scales in Western music generally consist of seven notes and repeat at the octave.
The scale degrees of a heptatonic (7-note) scale can also be named using the terms tonic, supertonic, mediant, subdominant, dominant, submediant, subtonic

Depending on the key signature, the notes of the scale move around, but the function of each degree, and relationships between them remain the same.
The Number System purpose is to use numbers instead of notes names in order to have an absolute system which works in the same way, no matter what key you're in.

So the Tonic will be always the 1, the subdominant will be always the 4, the dominant will be always the 5 etc.

This system have a lot of advantages, especially in the following areas:

- Musical studies (allows faster learning, especially scales and chords)
- Musical analysis (allows to understand the relationships between Melody & Harmony)
- Composition
- Improvisation
- Accompaniment (allows to transpose a song instantly)

Only seven degrees? Really??

Actually, you may encounter degrees higher than 7 (such as Upper-structure triads for example 9th, 11th, or 13th)
Sometimes this can be intimidating, but if you know perfectly the 7 degrees, you already know these other degrees!
Indeed, 9, 11 & 13 are the corresponding notes to 2, 4 and 6

And if you encounter an augmented fourth (# 4), you can easily deduce the answer too
In C major:
#4 = F#

a diminished fifth (b5)?
In C major:
b5 = Gb


A New System ?

It would be a mistake to believe that one system can replace another, and that we could avoid one for the benefit of the other.
Actually, they are complementary.
If you already have some knowledge of music, you probably already know the names of the notes, a few scales, some chords (from the most simple to the most complex) etc.

Are you able to indicate instantly the function and the position of each note in a scale?
and this, in any key? or in any chord?

You have probably heard a few times that the most important degrees are the I, IV & V,
or that the most used chord progression in Pop Songs is : I, V, vi(min) & IV
or that the fundamental cadence in tonal jazz music is : ii V I
etc. etc.

But what do these degrees refer to?
because, as we saw above, the corresponding notes are not the same depending on the key you’re in…
So, for example, if we know that in the major scale, the degrees I, IV and V are major and the degrees ii, ii and vi are minor, what are the corresponding notes in the F# major scale?
Can you answer this question instantly?

If you see a F#11 chord on your sheet, can you immediately put your fingers on your instrument and play only the 11th of this chord?

So, if you think that you need to improve your skills in this area
this software is for you :


Degrees - Number System- music

Very simple, and dedicated only to this objective

this training software will allow you to take a big step forward in your music learning
- no matter what your current level of music theory knowledge -

Take a quick preview of DEGREES


How it works?


The interface of DEGREES is very simple.
The software will automatically propose you a Tonic (1st degree of a scale) that will appear on the left side of the interface, then you will have to find the note corresponding to the degree shown on the right side.


To answer, just click as quickly as possible on the right note.

The software tells you whether your answer is correct or wrong.



If your answer is wrong, you need to make another proposal



if you are correct, the answer is validated and you can proceed to the next question.




At any time, during a training session, you can pause and view your results.
The results are displayed as a list that shows the time spent on each question.
So you can easily see the degrees on which you have to focus on.


The goal is to improve all the timings, in the most uniform manner possible, in order to control all the degrees smoothly and in all keys.


Anyway, you quickly realize that the smallest progress made during these training sessions, will have repercussions in your music learning, for example when you will try to learn new scales, some new chords or you will try to analyze the melodic/harmonic structure of a song.




Note: If you have a MIDI instrument, you can even answer directly from this one!
A Keyboard version, specially adapted to pianists/keyboardists, is also available.
