Professional Music Teacher's Testimonial
teacher of music for the past 30
years, the need for an
aid or device
for the student to assist
them with transposing, learning scale and
chord construction, intervals, etc. has been more and more apparent. I believe
MasterKey is the most
comprehensive aid yet devised.
In teaching theory, most of which is done without the instrument at hand, it is
very difficult to think
instantly and know the I, IV and V chord of
whatever key is being discussed, and even more difficult to know the relative
minor chords in any key.
The same can be said for knowing the note
names in any nominated scale, major or minor.
With MasterKey in front of you, these things can be seen at a glance whilst the
teacher is talking, thus
making it comparatively simple to follow the
MasterKey is something that can be used by anyone,
whether you are
doing a musicianship course for the sense of
achievement, or a 'serious' music student looking for maximum progress in your chosen career.
MasterKey has an added advantage, and that is that it is able to be used by
players of all instruments,
whether they be keyboard, brass, reed or

Does MasterKey come with full instructions?
Yes, every feature of your MasterKey is explained, with examples of
key-changes, scales, modes and
MasterKey's instructions are available for you to read online. Click here

Will I need to treat my MasterKey like a delicate
No, MasterKey is made of tough ABS plastic and will last you for years.
Does MasterKey produce sounds?
NO! MasterKey works by visually demonstrating its various functions.
Why is MasterKey not 'digital'?
A computer program or an app could give the answers which
MasterKey gives. The
great difference is that with the solid, physical
MasterKey you can see what is happening when you transpose, you can see
the 'shape' of scales,
modes and chords. It's that visualisation, that
mental image, that will soon be part of you. When it is, you will know that you
have thoroughly grasped
Is MasterKey portable?
Yes, very! MasterKey is 300mm (12") long and weighs
about 130 g ( 4½ oz).
It never needs batteries, so it's always ready to use, for as long as you like!
Is MasterKey easy to read?
Yes! MasterKey's 'straight-line' style means that all the information is 'right way
up', and easy to follow.
Why is MasterKey 'straight', not 'round' ?
