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.
These are the basic notes youâll be working with all the time: A, B, C, D, E, F, G. And each of these notes can be âmodifiedâ and sound a bit different than the original. This is done by either making the note a âSharpâ (#) or a âFlatâ (b). So you can have a C note, an A Sharp (A#) note or a B Flat (Bb) note, etc. One thing to note is this â some notes have different names, but are the exact same. For example, an A# (a sharp note) is the exact same note as a Bb (b flat note). Confusing right? But thatâs because of how music moves. Itâs easier to describe when looking at a piano.
