PowerShell and Bass Guitar

I recently decided to try my hand at a musical instrument.  The bass guitar seemed like a good fit for me so I picked it up started a with a few lessons.  I quickly realized that in order to have any success with it, I needed to memorize the fret-board.  Given my affinity for PowerShell, I decided to blend the two.  Following is a script that I threw in my profile to prompt me upon start-up for a few notes.

function Get-BassNote {            
 param($Count=2)            
             
 $BassNotes = @{             
      "Fret0" = @{             
        "String1" = {E}            
        "String2" = {A}            
        "String3" = {D}            
        "String4" = {G} }            
      "Fret1" = @{            
        "String1" = {F}
