Tuba- is the largest in the brass section and has the lowest pitch.

Percussion instruments- are played by striking the instruments with sticks or hammers while others are through shaking or rubbing like maracas.
Two classes
1. pitched
2. unpitched

Pitched Percussion

Timpani- known as kettle drums. It produces a thunderous effect when played continuously.

Xylophone- it can be of different lengths of wooden bars suspended on a frame of two rows, representing the white and black keys of the piano

Glockenspiel- known as bell-Lyra or orchestra bell. It sounds like little bells with a bright and silvery tone.

Tubular Bells- known as chime bars. They produce a church bell sound.

Unpitched Percussion

Bass Drum-the largest of the orchestra drums. It produces an awesome booming and thundering effect.

Snare drum- it produces a dry rattling and crackling sound

cymbals- two round metals held by leather straps fastened through the holes in their central domes. They clashed together with sliding motion or were struck by a stick to make a sound.

Others are castanets, gongs, tambourines, maraca, and triangles that belong to unpitched percussion.

Taxonomy

What is taxonomy?

Taxonomy is the branch of biology concerned with the grouping and naming of organisms

Biologists who study this are called taxonomists.

How did it start?

People wanted to organize their world, so they began grouping, or classifying everything they saw.

ü Things that swim.
ü Things that fly Things that crawl
ü Things that walk on four legs
ü Things that chew their food
ü Things that swallow food whole
ü Toxic things

Why classify?

To help us organize all of the millions of species we discover.
To give every species a name based on a standard method so scientists from different countries can talk about the same animal without confusion

Who is Carolus Linnaeus?

Carolus Linnaeus was a Swedish botanist.

Developed a 7-level (taxa) classification system based on similarities between organisms.

The 8 Taxons

What is the 8 classification of taxonomy?

The current taxonomic system now has eight levels in its hierarchy, from lowest to highest, they are species, genus, family, order, class, phylum, kingdom, and domain.

the classification system commonly used today is based on the Linnean system and has eight levels of taxa; from the most general to the most specific, these are domain, kingdom, phylum (plural, phyla), class, order, family, genus (plural, genera), and species.

Dear, how does it work?

There are 6 broad kingdoms.

Every living thing that we know of fits into one of the six kingdoms.

Each level gets more specific as fewer organisms fit into any one group.

Binomial Nomenclature

Bi means two

No means name.

Binomial nomenclature is a classification system using two names to identify an organism.

Scientific name

Genus-species name given to all organisms.

Canis familiaris is the scientific name for a domestic dog.

Canis is the genus name.

familiar is the species name.

This system uses a binomial nomenclature.

Genus…

A genus consists of a group of closely related species

Other animals in the Canis group include wolves and coyotes.

The genus name is always Capitalized.

Species...

A species consists of animals that can mate and produce fertile offspring.

Only domestic dogs are known as lupus.

The species name is always lowercase.

Which organisms are most closely related?

"The Tortoise and the Bird"

A tortoise was resting under a tree, on which a bird had built its nest. The tortoise spoke to the bird mockingly, “What a shabby home you have! It is made of broken twigs, has no roof, and looks crude. What’s worse is that you had to build it yourself. I think my house, which is my shell, is much better than your pathetic nest”.

“Yes, it is made of broken sticks, looks shabby, and is open to the elements of nature. It is crude, but I built it, and I like it.”I guess it’s just like any other nest, but not better than mine”, said the tortoise. “You must be jealous of my shell, though.

“On the contrary”, the bird replied. “My home has space for my family and friends; your shell cannot accommodate anyone other than you. Maybe you have a better house. But I have a better home”, said the bird happily.

Moral: Better a crowded hut than a lonely mansion.

Story trivia: The Tortoise and the Birds is a fable of probable folk origin, early versions of which are found in both India and Greece.
