You simply move the key down one half step
There is an infinate ways to modulate from C major to D major.
One way in which you can do this is use a "pivot chord" which is a chord that is similar in both keys. The chords similar between these two keys is E minor and G major. Simply play either of these chords between C and D.
Another is to play the dominant seventh chord of C major, G7, then move to the dominant seventh of D major, A7, then play D.
The most obvious method would be simply to slide up, as in a barbershop standard. It clearly depends on the style/genre of your music, of course. One method might be to go to chord VI (moving the A up to a B natural), then moving to E Flat as if it were a V-I progression in E Flat.
To modulate to any key, play dominant 7th chord from the new key you like to go to and you are there. Example: D major, than play Bb7 and than Eb-you are there.
The fastest way to modulate from A flat major to D major is to use an augmented sixth chord. Since an augmented sixth chord has a predominant function, it must resolve to the dominant chord in the new key and be built in the new key. There are 3 types of augmented sixth chords. An Italian augmented sixth chord is built with lowered sixth scale degree, unaltered first scale degree, raised fourth scale degree. A French augmented sixth chord has an unaltered second scale degree in addition to the notes in the Italian augmented sixth chord. A German augmented sixth chord has a lowered third scale degree in addition to the scale degrees that the Italian augmented sixth chord consists of.
Progression: B flat: I - N6(Flat II)
D: VI - V(7) - I
Chords: B flat - C flat (B) - A - D
Starting with a B flat major Chord, move to a Neapolitan chord (which is just a flat major II, or a chord built on the lowered second scale degree), which acts in D major as a borrowed VI chord. That easily resolves to V(7), which then resolves to the new tonic, D major.
If you're transposing a piece of music: Move all the notes up two semitones (one tone).
If you're modulating/changing key in the middle of a piece of music the key signature changes from two flats (Bb, Eb) to one flat (Bb).
One quick way to modulate to E flat major from F major would be to pass through a C minor chord (introducing the E flat into the key signature) and then to pass through a B flat 7 chord (introducing the A flat into the key signature), giving you three flats, the B flat, E flat, and A flat, required for E flat major.
If you are in E-flat major, firstly modulate to the dominant key of E-flat (which is B-flat major) and from there you can modulate to the fifth in B-flat major which is F major.
Modulate to E flat minor first!
It depends if you're playing a D flat major or a D flat minor chord. For D flat major, play D flat, F, and A flat. For D flat minor, play D flat, E, and A flat.
15 different key signatures exist. (no sharps or flats) = C major F sharp= G major F C sharp = D major F C G sharp = A major F C G D sharp = E major F C G D A sharp = B major F C G D A E sharp = F # major F C G D A E B sharp = C# major B E A D G C F flat = C flat major B E A D G C flat = G flat major B E A D G flat = D flat major B E A D flat = A flat major B E A flat =E flat major B E flat =B flat major B flat = F major
D-flat, F, A-flat for the triad
D flat major, or b flat minor. The flats are B, E, A, D and G, in that order.
A Major: A B C# D E F# G# A A minor: a b c d e f g a A-flat Major: a-flat b-flat c d-flat e-flat g a-flat
The way you would modulate from D major to Bb major would be passing through a D minor chord then modulating to G minor to get to Bb major.
You simply move the key down one half step
The fastest method could be a common tone modulation from D-flat to F, which is then the dominant of B-flat. The D-flat moves to C, the A-flat up to A-natural, and the F carries through.

Transpose the music down a major second.
I'd do a sneaky semitone raise to A, then its easy to shift from A to D probably using an A7
It depends if you're playing a D flat major or a D flat minor chord. For D flat major, play D flat, F, and A flat. For D flat minor, play D flat, E, and A flat.
