0:07 the first question you may ask is why do we even have transposing instruments in the first place for the sake of time I'll just say that it has a lot to do
0:14 with fingering so that players can switch between instruments without having to change how they play it for example changing between a B flat and an
0:21 EF flat clarinet what I'd really like to cover in this video is how to deal with transposing instruments whether you're a composer or a performer an educator or a
0:30 inductor you probably deal with these instruments on a regular basis to put it simply we have two different pitches the written pitch and the sounded pitch if
0:37 you're playing an instrument that's in C these pictures are the same there are some C instruments that are transposed either an octave above or below what is
0:45 written the treble instruments are written in octave lower than they sound and the base instruments are written in octave higher than they sound and here's
0:53 a list of all of the instruments that transpose up or down an octave if you have an instrument that's in something other than c we have to compensate for
1:00 the difference practically speaking there are two different types of transposition one going from concert pitch to a transposed pitch if for
1:09 example you have a piano Melody and you want to transpose it to trumpet or two we have going from the transpose pitch to the concert pitch if for example you
1:19 have a conductor scorer and you want to know the sounded pitch of an instrument so let's look first at BF flat instruments on these instruments a
1:27 written C is a sounded B flat B flat is 2 half steps lower than C or a major second so for B flat instruments you must compensate by writing two half
1:39 steps higher than the intended pitch here is Twinkle Twinkle Little Star on the piano which is a c [Music]
1:49 instrument if a trumpet a B flat instrument were to play that exact line here's what it would sound
1:58 like and just for fun here they are together that's bad so we compensate let's move every note of the trumpet
2:11 line up a major second looking at the accidentals we noticed the trumpet is now in D Major so let's fix the key signature as well if everything has gone
2:20 according to plan the two instruments should now be playing in unison but let's say that we have this particular line in front of us and we want to know
2:27 what the concert pitch of the trumpet is we simply go in reverse let's move every note of the trumpet part down a major second this shows us what the actual
2:36 sounded pitches of the trumpet are so when you see a B flat instrument that's listed as sounds a major second lower than written that's what that means
2:45 here's a list of all of the BF flat instruments next let's look at the E flat instruments we'll compensate the exact same way that we did for the B
2:53 flat instruments these instruments can either be written a minor third above or a major 6th below for these instruments a written C is a sounded E flat so to
3:04 transpose from a c instrument to an E flat instrument transpose all of the notes down a minor 3D or up a major 6th here's Twinkle Twinkle Little Star again
3:13 this time for piano and alto saxophone the alto saxophone sounds a major 6th lower than written so we'll take our alto sax part and we'll move it up a
3:21 major 6th and along with that we'll make sure to fix our key signature finally we'll look at the F instruments there are other notes that instruments can
3:28 transpose to but they're much less common the two most common F instruments are the French horn and the English horn which incidentally have nothing to do
3:36 with France or England but that's another video One Last Time here's our song these instruments both sound a perfect fifth lower than written so
3:45 we'll take our horn part and we'll move every note up by a perfect fifth and then adjust our key signature again if you're looking at a horn part you can
3:53 move every note down a perfect fifth to find the concert pitch finally here is a non-exhaustive list of instruments and how they
