How to easily transpose sheet music?
I`m trying to get better at reading and writing standard notation.
I was wondering how to transpose a piece from one key to another on sheet music , so I wrote a 2 bar phrase and tried to do it myself.
The first bar is just natural notes, the 2nd bar contains alterations.
I quickly realised that if there are no alterations , it is actually pretty easy , the problem seems to be that of transposing the sharps and flats.
In this first picture you can see the 2 bar phrase that I wrote , followed by the same phrase trasposed thru the circle of fiths (c major/g major/d major/a major/e major).
In this 1st picture the traspozitions were done automatically by the software and as you can see the software acomplished this by adding lots of natural signs. I can see why that is correct , but If I were to do this by myself It would take a long time since I`ll always have to remember which sharps are in the key signatures , recognise them on the score and calcultate the intervals in the piece etc.
So when I tried to do it myself on paper , I came up with what you can see in picture 2.
All I did was to move the phrase up or down the staff till it was in the right key. This worked really good for the keys of G and D , but when I got to the keys of A and E (and I didn`t notice this at first) , I realised that I have to make those notes double sharp in order for the phrase to be correct.
I play guitar, and on most stringed instrument you could just move the passage up and down the fingerboard and it would be automatically transposed.
Isn`t there a simple way to do this on sheet music as well ?
It seems that you can move the passage up and down the stave just well , but the sharp/flats and key signature accidentals really make this more complicated than it should.
Am I missing something obvious here ?
Thank you !

The trick is to resolve sharps you don't need/want, to avoid double sharps. That's basically what the automatic transposition does. Whenever an added sharp would create a new natural pitch, it uses that instead (including the natural marker).
Thus you could add sharps ad infinitum without ever having more than one on any note.
Consequently I also think it's a terrible idea to add flats in the original phrase, as that would leave you with a mix of sharps and flats after transacriptions, which is usually something to avoid. You WOULD use flats if you were going into the other direction on the circle (F, Bb, Eb..)
I interpret this melodic phrase of the two bars as: la ti do la, ta la ma re.
ta= ti flat and ma = mi flat (or what ever you will use as relative names for altered steps of do re mi)
it doesn' make sense to have here an A# followed by an natural A or a D# folloed by a natural D (except this was transposition were in 12 tone music where the enharmonic exchange wouldn't matter - but probably there wouldn't be a key assigned after the clef)
I agree with all those saying Bb and Eb instead of A# and D#, (etc. in all other keys) as they are leading tones solving to the I and IV - if this examples are melodic phrases and not just single notes in a 4/4 measure.
But for a guitarist I would propose to note both enharmonic names in the fret or tab.
Good spelling is important. Unless there's a compelling reason in the harmony to do otherwise, it's best to try to give each note its own line/space in the staff. If you write an accidental and then have to cancel it later in the measure, that's a good sign that maybe the music should be spelled differently.
On your first line, you should use B? and E? (unless the choice of chord dictated A? and D?). That would result in a B? on the second line as well, and then everything else in the computer-transposed version is good.
You shouldn't think of transposition as a mechanical act of sliding all of the notes the same direction by the same number of steps. You should try to think of it as recreating the music in a new key. But to do that effectively, you have to properly understand the music in its original key first. Picture the melody as scale degrees 6 7 1 6 ?7 6 ?3 2, and then it should be easy to apply that to any key. You could do the same with ?6 and ?2, but I think it's a little clearer in this form why that's less desirable.
The double sharps are correct. If we take the first line as being in C major, the second-to-last note is D#, the sharpened second note of the scale. The last line is in E major, the normal second note of that scale is F#, so sharpening it gives Fx (double sharp). And that's the key (sorry!) to transposing, knowing where each note is in relation to the key. (It doesn't even matter which key you take as base, as long as you're consistent. You could take the first line as being in F major, the last line as A major. The result would be the same, as long as the first note was the third of each scale.)
Yes, it's all about knowing your keys and scales.
Now, there's correctness and there's expediency - "the quality of being convenient and practical despite possibly being improper or immoral" (love that 'immoral' :-)) We might be tempted to make the Fx 'easier' by re-writing it as G nat. Once you're over the initial fear of a double sharp this can be unhelpful - it's much easier to read a scale when it LOOKS like a scale, a triad when it LOOKS like a triad.
