Hi Guys,
As you can tell by the title over the last week the itunes icon in the dock occassionally bounces once for no reason i can find.
What i can say is the following:-
1. No music is playing
2. No device is connected
3. nothing appears in notifications
4. Arrrrgh its just done it again
5. Itunes version
6. No downloads are involved
7. El Capitan version 10.11.6
8. It doesnt seem to happen when i am using the itunes window but does when using any other apps window
Any ideas guys

Seen this in sierra.
Have no idea either. Maybe frequency is lower than yours.
I just choose to ignore for good.

Try resetting the SMC :

Indicators that your SMC might need to be reset

After you perform normal troubleshooting, these symptoms may indicate that an SMC reset could be necessary:

  • The computer fans run at high speed, though the computer is not experiencing heavy usage and is properly ventilated.
  • The keyboard backlight behaves incorrectly on Mac computers that have this feature.
  • The status indicator light (SIL) behaves incorrectly on Mac computers that have this feature.
  • Battery indicator lights, if present, behave incorrectly on Mac notebooks that have a non-removable battery.
  • The display backlight doesn't respond correctly to ambient light changes on Mac computers that have this feature.
  • The computer doesn't respond to the power button when pressed.
  • A Mac notebook computer doesn't respond properly when you close or open the lid.
  • The computer sleeps or shuts down unexpectedly.
  • The battery doesn't charge properly.
  • The MagSafe power adapter LED doesn't indicate the correct activity.
  • The computer is performing unusually slowly, though it isn't experiencing abnormally high CPU utilization.
  • Application icons may bounce in the Dock for an extended amount of time when opened.
  • .....

My mistake its back again
Did you try starting in Safe Mode? Same behavior? After that, does the behavior continue in a normal start-up?

Safe mode may help you resolve or isolate problems that you’re having with your Mac.

When you start up in safe mode, your Mac prevents some software, such as startup items, from loading, and it performs a check of your startup disk. Your Mac may take longer to start up because of the check.

Edit : Earlier, sign out for iCloud was mentioned. Did you do the same for iTunes?

If Safe mode didn't work, have you tried disabling iTunes Helper in your user account login items located at :
System Preferences -> Users & Groups -> Select your user name -> Login items
