 ====== How noteMaps, rootMaps and, octaveMaps work together to produce a midi note ======
+** Overview: ** This tutorial teaches you how to use three different things, rootMaps, chordMaps, noteMaps, in Konduktiva to get the same effect in 3 different ways.
+**Things To Note:** This tutorial assumes you have already installed Konduktiva successfully using the [[https://github.com/renickbell/konduktiva|Konduktiva installation]] instructions and have read through and understood the [[:first_steps|first steps tutorial]]. The tutorial also assumes 2 things. One, Konduktiva has been assigned to the //K// variable. Two, user created a Musical Environment using the //setUpMusicalEnvironment// function using //K.defaultConfigurationObject// as the first argument and //'exampleMidiPlayer'// as the third argument then, assigned the output to the //e// variable.
+<code javascript>
+const K = require('konduktiva')
+let e = K.setUpMusicalEnvironment(K.defaultConfigurationObject,4,'exampleMidiPlayer')
+</code>
+rootMaps, chordMaps and, noteMaps work are combined to get the final midi note sent. I will use an example to explain it.
+<code javascript>
+let root = 'C'
+let octave = 8
+let note = 6
+let finalNote = K.Note.midi(root + octave) + note
+console.log(finalNote) //144
+</code>
+It is basically just an equation. So,  for instance we want the result 12 there are a few different ways can go about this.
+<code javascript>
+//Using root and octave:
+K.Note.midi('C' + 0) + 0
+//Using note:
+K.Note.midi('C' + -1) + 12
+</code>
