The Bass Clarinet should have the lowest pitch.. or if not the Bassoon
The Tuba
The Double Bass or the Contrabass is the lowest member of the string family.
Double Bass. (The Piccolo is- I believe- the highest sounding member of the woodwind family of standard orchestral instruments whilst the Double Bass is the lowest sounding member of the String family).
It's not the bass clarinet.The octocontrabass clarinet (also known as octo contrabass clarinet, octo contra bass clarinet, or subcontra bass clarinet) is the largest and lowest member of the clarinet family. It is pitched an octave below the contrabass clarinet, or three octaves lower than the standard B♭ soprano clarinet.The Guinness Book of World Records lists the octocontrabass clarinet as having the lowest range of any orchestral instrument, capable of playing B♭-1 concert pitch (the B♭ below the lowest note of the piano).
The bass bassoon
The contrabassoon and contrabass clarinet act as the lowest voices of the woodwind ensemble. The Guinness Book of World Records lists the octocontrabass clarinet as having the lowest range of any orchestral instrument, capable of playing B♭-1 concert pitch (the B♭ below the lowest note of the piano).
The lowest pitch, and therefore largest, is the tuba.
The longer the clarinet the lower the pitch or sound it makes. The shorter the clarinet the higher pitch it makes. The most common clarinet is a Bb (B flat) Clarinet or a bass clarinet which is longer and lower. Another common clarinet is an Eb (E flat) clarinet which makes a higher pitch or sound. As far as i know, they all have the same fingerings. The only difference is your embouchure (how you position your mouth) and the sound/pitch it produces.
Larger instruments produce lower pitches; the Bass Clarinet, being one of the largest types of clarinets, produces one of the lowest sound.
It depends how you mean:If you mean when the instrument is playing a concert pitch A then some sound the same as other and would be in groups:Piccolo,Flute, clarinet and oboeBassoonIf you mean their pitch range for their highest note:Piccolo,Flute,Oboe,Clarinet,BassoonPitch for their lowest note:Piccolo,Flute,Oboe,Clarinet,Bassoon(this is only using the most simple of woodwind instruments)
The largest brass instrument in the tuba. It is also the lowest in pitch. The largest playable tuba in the world was exhibited in Frankfurt, Germany at nearly 8 feet tall.
The Clarinet Is both pitches it depends how you blow it
