Nineteen Skeletal Duets for Trombones is a set of duets of easy to moderately difficult specifically for teachers and students in private lessons. The first 15 duets are arranged from Fifteen Safari Duets for Tubas which was composed in 1989 for playing with my tuba students at Berklee College of Music. They are at different levels of difficulty and in various styles so that we always had duets to play no matter what was the ability of the student. The additional four duets were added in 2020 for trombones for this set. The title of each duet is also a name for a bone in the human body, hence the name Skeletal Duets. There is something in each duet for students to learn: the basics of tone production, rhythms, melodic phrasing, jazz, graphic notation, etc. Most are sight readable and some have been performed in concerts. Nineteen Skeletal Duets for Euphoniums are the same duets but in treble clef. Twenty-two Skeletal Duets for Hornsuses the first 19 of the trombone set with three additional duets added. Some of the trombone and horn duets are in the same key so they can be played together.

1. Cranium
This duet presents the cantabile ?singing? style as studied for playing the trombone. I find that this duet helps the student much like the melodies of Borgodni (Rochet) etudes.

2. Stirrup
This duet provides an opportunity to read basic rhythms and articulations. I find that the more advanced students can read in a faster tempo while the less skilled students work best in the slower tempos ? a common choice for all of the duets.
3. Humerus
This waltz helps the student match phrasing in a cantabile setting. There are a few instances where the teacher (playing the first part) plays a phrase then the student plays a similar phrase.
4. Vertebra
This is in a ?rock? style with syncopated rhythms with cantabile melodies. Articulations are especially important in this duet.
5. Axis
Legato scales and syncopated rhythms are the features of this duet. This is a good exercise for legato playing on trombone, especially when the legato tongue is needed versus when the trombonist does not need to tongue when moving across partials.
6. Tibia
This duet alternates in rock style and swing. Articulations and manipulation of ?swing? rhythms are important.
7. Clavicle
The key of A for this duet provides variation for the students.
8. Fibula nd
This duet uses the easiest of rhythms and range, especially for the 2
9. Scapula
This duet is non-metric and uses graphic notation. This was a favorite duet of my students as many had never experienced this notation before.
10. Atlas ndThis is an Invention in the Bach style. This is probably the best duet to play when the 2 part is played by bass trombone.

(student) part.

11. Radius
This duet is in a ?Medium Swing? jazz style. Each part has a chance to play a little bit of a ?walking? bass line. Articulations and manipulation of ?swing? rhythms are important in this duet.
12. Femur
This duet works on double time and half time tempo changes.
13. Patella
This is another duet that includes graphic notation. In this duet ?Free rapid legato lines? are used.
14. Anvil
This gallop displays different types of articulation.
15. Hammer
This duet is in the style of a fanfare.
16. Rib
This duet is a melody, ?Magallon Blues?, that I originally composed when I taught at a summer music camp in Magallon, Spain. In that camp each of the students would practice playing a jazz solo. This duet also has jazz chord changes so you can add piano or guitar. The use of drums is also an added option.
17. Sacrum
This duet is a short arrangement of Mozart?s ?Eine Kleine Nachtmusic?.
18. Ulna
This duet is a short arrangement of the traditional Irish folk song ?Londonderry Air?, more commonly known as ?Danny Boy?.
19. Ilium
This duet is a short arrangement of the Beethoven?s song ?Ode to Joy? which represents the triumph of universal brotherhood against war and desperation.

Fifteen Safari Duets for Tubas was composed for playing duets with my tuba students. The fifteen duets are at different levels of difficulty and various styles so that we always had duets to play no matter what ability of student. There is something in each duet for students to learn from the basics of tone production, rhythms, melodic phrasing, jazz, graphic notation, etc. Most are sight readable and some have been performed in concerts. They are all fun to play. Although for tubas, they may be played on any instrument.

In 1988 I spent a month in Kenya on safari and experiencing the African wildlife and culture, thus the inspiration for these duets that were composed soon after the trip in 1989 and 1990 and have been a regular part of my teaching ever since. Four of these duets are recorded on the compact disc ?Tuba Safari? (Troy 1173) on Albany Records.

1. Elephants at Stave

This duet presents the cantabile style studied for playing the tuba. I find that this duet helps the student much like the melodies of Borgodni etudes. There are more elephants in Tsavo than anywhere else in Kenya. It was not uncommon to see large families of thirty elephants at a time.

2. Gallop ? Thompson Gazelle at Amboseli

This duet provides an opportunity to read in a sharp key, D major, as well as basic rhythms and articulations. I find that the more advanced students can read in a faster tempo and other students can work in a slower tempo ? a common choice in all of the duets. Large herds of playful Thompson Gazelle were a usual occurrence in most of the game parks in Kenya.

3. Rhinos at Nairobi Game Park

This waltz helps the student match phrasing in a cantabile setting. There are a few instances where the teacher (playing the first part) plays a phrase then the student plays a similar phrase. The rhinoceros is a very noble animal that can grow to more that 1,000 pounds and is known for its horn. The Nairobi game park is located just outside the city, giving a sense of surrealism to the panorama.

4. Giraffes at Nairobi Twiga Park

This is in a ?rock? style with syncopated rhythms and cantabile melodies. The Nairobi Twiga park is just outside the city and is the only place where one can feed the giraffes. Along with their long necks they have very long tongues.

5. Warthogs at Ngulia

Legato scales and syncopated rhythms are the features of this duet. Warthogs have tails that are held upright when they run.

6. Baboons at Kiliguni

This duets alternates in rock style and swing. Baboons are sometimes a problem because they will try to steal food from the tourists? tables. They will work together where one causes a diversion while the others steal.

7. Pastoral ? Cape Buffalo at Samburu

The key of A for this duet gives variation for the students. Cape Buffalo are in large herds on the savanna. The Samburu Lodge dining area was built next to a watering hole. At the beginning of breakfast there were no animals, but in fifteen minutes more than 500 cape buffalo were at the water hole.

8. Song - Hippos at Mzima Springs

This is the easiest of rhythms and range of the duets, especially for the 2nd(student) part. Hippopotamuses can grow up to 4,000 pounds and spend most of their time sleeping in the water during the day. At night they go on land to hunt.

9. Leopards at Kimana Lodge

This duet is non-metric and uses graphic notation. This was a favorite duet of my students as many have never experienced this notation before. The leopard is a large predatory cat that usually hunts at night.

10. Colobus Monkeys at the Ark

This is an Invention in the Bach style. The Ark is a building that was built in 1969 at a watering hole for tourists to watch wildlife. The colobus monkey is black with white on its forearms and chest.

11. Zebra Migration at Masai Mara

This duet is in a ?Medium Swing? jazz style. The great migration between the Masai Mara and Serengeti involves about two million wildebeest, zebras and other animals every year. It is considered one of the most impressive natural events worldwide.

12. Ostrich at Samburu

This duet works on double time and half time. The ostrich is the largest bird in the world. In Samburu there was an ostrich that hung around the lodge, her name was Margaret. She was very friendly with everybody but she would steal your hat.

13. Cheetah at Voi

This is another duet that includes graphic notation. The cheetah can run up to 80 miles an hour when chasing after prey. When not hunting prey it often walks very slowly.

14. Gallop ? Gerenuk at Buffalo Springs

This gallop displays different types of articulation. The gerenuk is an antelope with a slightly extended neck so it can eat higher leaves from trees.

15. Lions at Mara Sopa

This duet is in the style of a fanfare. The lion is considered the king of the savanna.
