Is there a common leap that is used in music when changing key.
Sweet child o mine solo goes from D major to E minor ( I think!!) but is there a model leap? Or can you change from any one key to another successfully? Or is there a sweet change that it mainly used?

No exactly. I'll explain the sweet child of mine modulation which should explain everything. First take the D major scale and look at all the chords that exist in that key.

Dmajor / E minor / F#minor / G major / A major / B minor / C# dim.

Now take the chords that exist in E minor.

Eminor / F#dim / G major / A minor / B minor / Cmajor / D major.

Now to move from the first key to the second is done by taking a common chord that exists within both keys and use that as a pivot point to go from the first key to the second key. Looking at the chords that exist between both keys, you would see 4.

D major, E minor, G major, and B minor.

Since when you write something in a particular key you should always end with the tonic. In this case starting in the of D major, it's D major. So what they did was just end a part on D major and then slide right up to any of the the 4 chords meantioned above and start the new key with that chord. Most likely E minor or B minor.

If you study this with all the keys, you can see that you can get from one key to a good number of keys using this process of modulation. The others that don't work out would be a dramatic move, which sometimes thats what you want.

When using modulation, it's best to end the first key by playing the iv-v (IV-V) chord progression that exists in the new key. It's not a rule but it often gives the best results of being smooth. Try using the harmonic minor or harmonic major scale to change the V chord to minor or major.

Hope that helps.

Some people prefer a smooth change by placing a small melodic line before changing the key , others just change without previous notification !
It's up to you.

ii V progressions will literally let you jump from keys that have no correlation w/each other
ex: A-7 D7 / D-7 G7/ Bb-7 Eb7/ Db-7 Gb7 / Cbmaj7//

Dominant chords are the key. Direct modulation is not the norm, though not unusual, can be used. Dominant chords can also fake a modulation. It's what makes us human.
