I replaced our front door bell today, as it sounded like someone with badly fitting dentures playing a comb and tissue paper. To my joy, the new one has the first few bars of Beethoven's 9th. However, its secondary mobile unit plays in a slightly lower pitch and fractionally behind. Somewhat jarring, and not in a Jean-Michel kind of way. 
The main is a dahlia with photo bombing bee. 

Many thanks to Ingeborg for hosting.
