The DJ digital music controllers emulate the traditional mixer/turntable/CD turntable set up. Most controllers are small and light weight computerized systems that can be stand alone or plug into a laptop computer via USB connections. Some models are powered from the computer so you don’t need additional power plug ins.

The use of DJ digital controllers with DJ software allow for a more mobile system for setting up quickly and easily to entertain at almost any event for home, mobile and Club DJs. DJ Controllers and software allow for extreme creativity when pounding out dance music mixes. The controllers allow DJs to customize the music and lighting at the touch of a button or switch. DJs can use digital music controllers to put in cue points and give simultaneous commands with a touch of the button, toggle, or even laser beams.

DJ controllers vary by skill level and complexity for the beginner or pro. Controllers can act like musical instruments in that you can play a variety of instruments and sounds at the touch of a trigger button. Many come with preset software allowing the user to just jump right in and start mixing and recording their own music.Controllers like The Beamz allow you to control lights as well as sounds, FX,loops and much more.

When you are learning chords to accompany songs, you will probably make use of your chord charts showing you chords that use all the guitar’s strings which could have inspired me to take Piano Lessons at Pianoforall and for me to do this Rocket Piano Review. But if you want to get into playing solos start with the three note chords called triads. The three notes in a triad are the basic notes of your chord, so by learning triads you will begin to see how the guitar chords are structured. Also you can move your triads up and down the fret board to make new chords.

Here’s an example:

The chord of A Major is made up of the notes A C# and E shown in tab form as:

E—————————————–
B————–2————————–
G————–2————————–
D————–2————————–
A—————————————–
E—————————————–

Move that shape one semitone (one fret) up the neck and you get A# or Bb.

E—————————————–
B————–3————————–
G————–3————————–
D————–3————————–
A—————————————–
E—————————————–

One fret higher is B Major.

E—————————————–
B————–4————————–
G————–4————————–
D————–4————————–
A—————————————–
E—————————————–

This shape played anywhere on the neck will give you a major chord. The fret it is played at tells you the key it is in.

Here are the notes for the triads of the basic chords:
C Major – C E G
D Major – D F# A
E Major – B E G#
F Major – C F A
G Major – G B D
A Major – A C# E
B Major – B D# F#

Now the minor chords:
C Minor – C Eb G
D Minor – D F A
E Minor – B E G
F Minor – C F Ab
G Minor – G Bb D
A Minor – A C E
B Minor – B D F#

Naturally, there will be some points you need to make a little clearer, so you will find more descriptions and illustrations available for free on the internet.
