Takes a little 'getting used to.' Pitch is controlled by the amount of water installed. Tongueing can provide a wide variety of calls. Recommended.
Bird calls will be needed
Basic bird "noise" comes easily; instructions advise on more complex calling. Bird "trills" take some practice (at least for this user), with the volume of water/liquid required in the chamber a matter of some experimenting. Sound clarity is superb, as is the compact design.

Toy Symphony Accessory
Provides the warbling tweet that I hear in Toy Symphony recordings. Works fine if you add the right amount of water (determine through trial and error) and blow firmly, steadily, but not too hard. Made in England with nice metal top and plastic base.
