Consisting of two relatively large medleys. Although written to be easy to play, the difficulty is somewhat high, comparable to Czerny 40 Etudes.

Extravaganza, in a dictionary sense, means a collection of various musical pieces. It carries nuances of boisterous liveliness and a miscellaneous, hodgepodge quality, which in Japanese can be described as “gōsei” (grand). True to this image, familiar melodies are freely transformed and appear one after another with a casual expression.

1. American Medley

Based on patriotic songs, folk songs, and popular tunes, even the American national anthem makes an appearance. The opening section is Andante, in 4/4 time, and in A major. It seems there's no need to explain these to Americans, so while the individual song titles are not indicated in the score, they are listed below for convenience.

• The Battle Hymn of the Republic
• Dixie
• Working on the Railroad
• Yankee Doodle
• America the Beautiful
• The Star-Spangled Banner (American National Anthem)
• Oh! Susanna (Foster)
• Turkey in the Straw
• Jeanie with Brown Hair (Foster)
• Camptown Races (Foster)

2. Mother Goose Medley

A comprehensive collection of children's songs, nursery rhymes, and lullabies. The opening section is Moderately fast, in 4/4 time, and in F major. For songs unfamiliar in Japan, only the original titles are listed.

• London Bridge is Falling Down
• A Tisket a Tasket
• The Farmer in the Dell
• Mary Had a Little Lamb
• ABC Song
• Rock-a-bye-Baby
• Silly Halloween Song
• No No Swimming Song
• Little Boo Beep

The overall speedy development keeps it engaging, and the playful touches are endearing. The surprisingly romantic turn in the musical style from the middle of the second piece onwards is also worth listening to.
