2. In this chapter, you learned that some pathogens must attach to host cells to cause disease. To accomplish this, molecules on their surface (adhesins or ligands) recognize and attach to molecules (receptors or integrins) on the surface on certain host cells.
So a chromatic note, is any note you play that is not in the scale you are playing. They are also a great way to practice, especially if you are going through the pentatonic scale. Try adding one of these outside chromatic notes to your scale, and see how it sounds above the chord you are playing over.
The smallest interval in use in the Western musical tradition is the semitone (also called half step). It is the interval between any note and its nearest neighbour on the keyboard. Two semitones together form one tone (or whole tone or whole step). Audio 1 From C to C# (or Db) is a semitone.From C# to D is also a semitone. Therefore from C to D is 2 semitones or 1 whole tone. (Down-Up-Top-Links) JT 1.2 - The Chromatic scale There are a total of twelve notes within an octave, represented by the 12 keys on the keyboard. All notes are spaced at semitone intervals.-note Diminished scale (tone-semitone-tone-semitone -) This scale starts with a tone between the tonic and 2nd note, then a semitone between the 2nd and 3rd notes, again a tone between the 3rd and 4th note, and so on. Audio 5 In Jazz this scale is used for improvisation over diminished chords (see Lesson 15).
