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.
You should never use the same letter name three times in a chromatic scale, so we can't write C flat, C natural then C sharp! In fact, the easiest way to write out a chromatic scale using this method is to write in two of each note between the start, end and middle notes you've already worked out.he notes we have found are Eb, D, Eb, E, F. The E flat is repeated, so we should ignore the first one, which will give us four notes in total: D-Eb-E-F. These are four consecutive notes which are part of a chromatic scale.
